I installed and played the beta last night for about an hour no problems at all, but now I can't even open the beta because it says my video card is unsupported. I have an nvidia geforce gtx 260. If the video card was really unsupported then I shouldn't have been able to play last night. The video card also isn't in the list of unsupported video cards. What's up

Pressing ESC when this message pops up is the work around.
