Ok, from the message, we can see it's a TypeError. The shared variable's type is float32, but the update rule's type is float64. I have noticed that u have used a GTX GPU, whereas i haven't.
I think, the problem is the type of your system and the GPU is not the same, one is 64bit and one is 32bit.
First method, u can change the .theanorc file which contains your GPU info, change the floatX to float64. Second method, u can just leave the GPU out, just use your cpu.
I hope these can solve your problems.

it works by change .theanorc
floatX = float64 --original is 32
