Sorry to hear that. I double checked the build and it works for me.
Without additional context I can only make basic suggestions.
- You may not have enough vram, what is your GPU? I recommend having at least 2gb. Are there lots of other apps running in the background consuming available video memory like adobe software?
This is likely the culprit if you're unable to play the full game, but able to play the demo.
- Have you tried running "dxwebsetup.exe" in the game folder?
Cheers
