I have the same problem, refusing to start in D3D.
Anyway my Mobile X1400 get the all black textures except inside structures and I can see the menus and stuff.
Does the things described here correct the problem? Or should I stay with 8.37? (or should I move to 8.40?)
I had great faith in this latest release from ATI but since I only need my graphic card for WoW, no use to change if I can't play.
