Hi guys,
I am having the same problem. Weirdly, when using the builder, MissingFunctionException says that glActiveTextureARB is missing, when using the coder, it says that glActiveTexture is missing.
I understand that this is not a PsychoPy problem. However, it worked the last time I used it, less then a month ago. However, I was using version 1.94 and now I updated it to version 3.5.
I tried to go back to back to 1.94 but the problem now remains. It might be that my driver updates itself?
I am using Window 10.
Is anyone able to explain to me in plain English (e.g. change your driver would not be useful 
how I can solve the problem?
Thanks and best wishes
Ale
