I am working in windows phone 8 app. My windows phone 8 emulator was working properly but it stopped working when i installed the Oracle Virtual Machine for learn something by it but when i tested my windows phone app than app was successfully build but Windows phone 8 emulator was not loading. Than what i did, i opened Hyper-V Manager and started emulator and kept the checkpoints during running emulator. My checkpoint Steps i am writing .
1) Windows icon visible and took 2 minutes to invisible.
2) Blank screen visible continuously.
3) It automatically closed.
I tried to run wp8 emulator from my app as well as Hyper-V manager many times. But all wasted. :(. Need helpful suggestion and solution to resolve it.
