Error while using Conv2DLayer with lasagne NeuralN

I have windows 8.1 64bit and use recommended here http://deeplearning.net/software/theano/install_windows.html#installing-theano python win-python distribution (python 3.4). I've went through every step of tutorial (excluding CUDA stuff and GPU config), uninstalled everything and did it again but my problem persists. I am trying to build convolutional neural network using Lasagne. Every layer I've tested so far is working - only Conv2DLayer throws errors. Code is as follows:

net2 = NeuralNet(
layers=[
    ('input', layers.InputLayer),
    ('conv1', layers.Conv2DLayer),
    ('pool1', layers.MaxPool2DLayer),
    ('hidden4', layers.DenseLayer),
    ('hidden5', layers.DenseLayer),
    ('output', layers.DenseLayer),
    ],
input_shape=(None, 1, 96, 96),
conv1_num_filters=32, conv1_filter_size=(3, 3),
pool1_pool_size=(2, 2),
hidden4_num_units=500, hidden5_num_units=500,
output_num_units=30, output_nonlinearity=None,
update_learning_rate=0.01,
update_momentum=0.9,
regression=True,
max_epochs=400,
verbose=1,
)

Below I have pasted the error that I get. I suppose that something is wrong with gcc (I got exact version from tutorial) but can't really figure out what is the problem. I have bleeding edge versions of lasagne/theano. I've tried both Anaconda and WinPython distributions. I've tried both with python 2.7 and 3.4 and can not really find any solution to this problem. Nets with only dense/maxPooling layers are running just fine. I would be grateful for any suggestions that would help me to resolve this issue.

I managed to solve my issue by following steps given by IshanAntony on this website https://www.kaggle.com/c/otto-group-product-classification-challenge/forums/t/13973/a-few-tips-to-install-theano-on-windows-64-bits/98833 . Apparently Theano had problem with linking BLAS correctly so I downloaded and used open-BLAS and error vanished (links and steps needed to download and configure OPEN-BLAS can be found in IshanAntony's answer).
