This can happen if you try to run on a GPU that's too old to support this code. 
I wasn't clear in my disclaimer on the Compiling page, but this code actually 
requires a GPU with shader model 3.5 capability. This includes K20, K40, 
GeForce Titan, etc. But it *does not* include K10 or GeForce 680. These will 
not work.

Thanks. I changed GPU from M2090 to K20 and It's working now.
