I have it, I have used it a bit. It does work, but there is a multi-thread issue that is yet unresolved. If you turn multi-threading off it should work. It actually works with multi-threading, but not with your own 3d shaders.Not sure about that update tho running as a demo. Your problem is something else. I can't remember, but can you hit ok instead of cancel? Send an email to Julien he can confirm. I have c5pro.

No need to think outside the box....
