I know others have had this error too but browsing the forum didn't get me an answer on how to fix this...
I've tried installing new drivers for my Tornado GeForce MX 4000 graphic card but without luck.
I've also tried "DH Driver Cleaner Professional Edition" but without luck.
All I can remember doing after the last time my q2 worked was installing DirectX9
and I dunno much about graphic cards, drivers, or anything else surrounding this

and I haven't changed my CFG...
