Sony remote app on C#. stucked after trying livevi

Question

So here is my question. I am trying to use the sony remote camera API SDK as a guide for developing a simple program in Visual studio using C# and controlling a SDCQX-10. I tried to use the kz-remote app... but couldn't get around with it. So I decided to get it done by using network sockets. It was wonderful, at the beginning, but after a while I decided to give it a try to liveviewing... Then everything crashed. I mean, by everything, The camera stopped responding. I managed to get the lenses "closed and opened again (retract)" by removing the battery and inserting it again and switching the camera on, but then, when trying to take a picture the camera stopped responding again. OK so, after some workaround here are the symptoms (camera is Updated to V3.0 firmware):

-The camera turns on normally, by manual control you can zoom in and out -When the shutter is pressed it takes a while for it to make the "take picture" sound (Although no picture is taken) -After the "Take picture" sound is heard, the red led indicator (Access lamp) keeps lit (ON) -After the shutter is pressed, the camera does not respond (The zoom in/out is disabled, shutter does not respond either) -When turning off the lens doesn't retract

When using the PlayMemories Android App (Version 5.7.0, spanish. Android V. 6.0.1 Asus Zenphone 2 Laser (ASUS_Z00TD) *Previously working OK with Playmemories)

-The camera connects "normally" -No liveview is available (black screen with controls superposed) -Zoom in/out works from the android device -Something that will translate as "Cannot obtain direct visualization image" is displayed after some time -When remote shutter is pressed all the symptoms above described for the manual shutter happen as well.

Finally, I tried to check what was happening when using the program: I use the following code on a button to connect the camera (SDDP to discover the camera and retrieve the information)

private void button2_Click(object sender, EventArgs e)
    {
        IPEndPoint LocalEndPoint = new IPEndPoint(IPAddress.Any, 60000);
        IPEndPoint MulticastEndPoint = new IPEndPoint(IPAddress.Parse("239.255.255.250"), 1900);

        Socket UdpSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
        UdpSocket.Bind(LocalEndPoint);

        textBox1.AppendText("UDP-Socket setup done...\r\n");

        string SearchString = "M-SEARCH * HTTP/1.1\r\nHOST:239.255.255.250:1900\r\nMAN:\"ssdp:discover\"\r\nST:urn:schemas-sony-com:service:ScalarWebAPI:1\r\nMX:3\r\n\r\n";

        UdpSocket.SendTo(Encoding.UTF8.GetBytes(SearchString), SocketFlags.None, MulticastEndPoint);

        textBox1.AppendText("M-Search sent...\r\n");

        byte[] ReceiveBuffer = new byte[64000];

        int ReceivedBytes = 0;

        while (true)
        {
            if (UdpSocket.Available > 0)
            {
                ReceivedBytes = UdpSocket.Receive(ReceiveBuffer, SocketFlags.None);

                if (ReceivedBytes > 0)
                {
                    textBox1.AppendText(Encoding.UTF8.GetString(ReceiveBuffer, 0, ReceivedBytes));
                }
                break;
            }
        }
    }

After which I get this response:

I used this script on another button in order to test different functions:

private void button3_Click(object sender, EventArgs e)
        {
            try
            {
                // Create a request using a URL that can receive a post. 
                WebRequest request = WebRequest.Create("http://10.0.0.1:10000/sony/camera ");
                // Set the Method property of the request to POST.
                request.Method = "POST";
                // Create POST data and convert it to a byte array.
                string postData = "{\"method\": \""+textBox2.Text+"\",\"params\": [],\"id\": 1,\"version\": \"1.0\"}";

                byte[] byteArray = Encoding.UTF8.GetBytes(postData);
                // Set the ContentType property of the WebRequest.
                request.ContentType = "application/x-www-form-urlencoded";
                // Set the ContentLength property of the WebRequest.
                request.ContentLength = byteArray.Length;
                // Get the request stream.
                Stream dataStream = request.GetRequestStream();
                // Write the data to the request stream.
                dataStream.Write(byteArray, 0, byteArray.Length);
                // Close the Stream object.
                dataStream.Close();
                // Get the response.
                WebResponse response = request.GetResponse();
                // Display the status.
                textBox1.AppendText(((HttpWebResponse)response).StatusDescription);
                // Get the stream containing content returned by the server.
                dataStream = response.GetResponseStream();
                // Open the stream using a StreamReader for easy access.
                StreamReader reader = new StreamReader(dataStream);
                // Read the content.
                string responseFromServer = reader.ReadToEnd();
                // Display the content.
                textBox1.AppendText(responseFromServer);
                var fot = responseFromServer.Substring(20).Split('\"').FirstOrDefault();
                //textBox2.AppendText(fot);
                // Clean up the streams.
                reader.Close();
                dataStream.Close();
                response.Close();
                webBrowser1.Url = new Uri(fot);
                // Follow intruction to try to visualize the image
                //var client = new WebClient();
                //client.DownloadFile(webBrowser1.Url, @"c:/foto.jpg");
                //using (MemoryStream mem = new MemoryStream(dat))
                //{
                //    using (var im = Image.FromStream(mem))
                //    {
                //        pictureBox1.Image = (Bitmap) im;
                //    }
                //}
                //pictureBox1.Image = Bitmap.FromFile(@"c:/foto.jpg");
            }
            catch (Exception ex)
            {
            }
        }

It worked fine to take pictures, I commented the few last lines, I used them to retrieve the picture (I'm leaving them there because until then it was working OK, for taking the picture and visualizing it)

SO, i have no data before the crash (Shame on me)... But after, here are some responses for the API:

actTakePicture

OK{"error":[40403,"Long shooting"],"id":1}

then (When pressed a second time and on)

OK{"error":[5,""],"id":1}

awaitTakePicture

OK{"error":[40403,"Not Finished"],"id":1} (Keeps on this after taking the Picture)

or

OK{"error":[1,""],"id":1} (It appears a bit random in between the above and this one when no picture has been taken)

getEvent

using: \"params\": [false]

OK{"id":1,"result":[{"names":["getMethodTypes","getAvailableApiList","setShootMode","getShootMode","getSupportedShootMode","getAvailableShootMode","setSelfTimer","getSelfTimer","getSupportedSelfTimer","getAvailableSelfTimer","setPostviewImageSize","getPostviewImageSize","getSupportedPostviewImageSize","getAvailablePostviewImageSize","startLiveview","stopLiveview","actTakePicture","startMovieRec","stopMovieRec","awaitTakePicture","actZoom","setExposureMode","getExposureMode","getSupportedExposureMode","getAvailableExposureMode","setBeepMode","getBeepMode","getSupportedBeepMode","getAvailableBeepMode","setCameraFunction","getCameraFunction","getSupportedCameraFunction","getAvailableCameraFunction","setStillSize","getStillSize","getSupportedStillSize","getAvailableStillSize","actFormatStorage","getStorageInformation","setTouchAFPosition","cancelTouchAFPosition","getTouchAFPosition","getSupportedExposureCompensation","getSupportedWhiteBalance","getSupportedIsoSpeedRate","actHalfPressShutter","cancelHalfPressShutter","getApplicationInfo","getVersions","getEvent"],"type":"availableApiList"},{"cameraStatus":"IDLE","type":"cameraStatus"},{"type":"zoomInformation","zoomIndexCurrentBox":0,"zoomNumberBox":1,"zoomPosition":0,"zoomPositionCurrentBox":0},{"liveviewStatus":true,"type":"liveviewStatus"},{"liveviewOrientation":"0","type":"liveviewOrientation"},[{"takePictureUrl":[],"type":"takePicture"}],[],{"triggeredError":[],"type":"triggeredError"},{"motionRecognition":"None","sceneRecognition":"None","steadyRecognition":"None","type":"sceneRecognition"},{"formatResult":"","type":"formatStatus"},[{"numberOfRecordableImages":1228,"recordTarget":true,"recordableTime":-1,"storageDescription":"Storage Media","storageID":"Memory Card 1","type":"storageInformation"}],{"beepModeCandidates":["Shutter Only","On","Off"],"currentBeepMode":"On","type":"beepMode"},{"cameraFunctionCandidates":["Remote Shooting","Contents Transfer"],"currentCameraFunction":"Remote Shooting","type":"cameraFunction"},null,{"checkAvailability":true,"currentAspect":"4:3","currentSize":"18M","type":"stillSize"},{"cameraFunctionResult":"","type":"cameraFunctionResult"},null,null,{"currentExposureMode":"Intelligent Auto","exposureModeCandidates":["Intelligent Auto","Superior Auto","Program Auto"],"type":"exposureMode"},{"currentPostviewImageSize":"2M","postviewImageSizeCandidates":["2M","Original"],"type":"postviewImageSize"},{"currentSelfTimer":0,"selfTimerCandidates":[0,2,10],"type":"selfTimer"},{"currentShootMode":"still","shootModeCandidates":["still","movie"],"type":"shootMode"},null,null,null,null,null,null,null,null,null,null,null,null,{"currentSet":false,"currentTouchCoordinates":[],"type":"touchAFPosition"}]}

Well, I really hope that is enough information. And I really hope somebody can help me with this!!!! A similar thread I found is: Sony RemoteAPI delays after starting Liveview But there were no answers. Thank you all!!!
