Black screen after start

[PurePwnage]

The screen is black after i start the game, but I can hear some music. ALT+F4 works. I'm using Win7 with ATI 5800 I think. Anyone knows a fix?

It may happens if anti-aliasing is enable. Switch off this graphical option in the Performance/Quality settings of your video driver and try again.
Selecting "Application-controlled" is also ok as it will switch off antialiasing.

Hope it will solve your problem.
