This code works, and uses shaders. But it looks like almost anything else I try and run which uses plugins or shaders doesn't work.

I'll do some more checking and see if I can produce a list of problematic plugins, but this is the only program which uses shaders I've managed to get to run. Most programs just don't start at all, (no errors) and some crash with the program has stopped error.
I've attached the source and my compiled exe file. Have a looksy and see if the exe will run for you.
