And therein may lie the problem. I think I recall other people having problems running games with DirectX 10, especially if your video card is not a Dx10 compatible card. Unless you have just recently bought or built your system, and spent a small mint on video card and such, I doubt that you have a Dx10 card, but hey! you may have.
If you could play GW (or any other game written in the not-too-distant past) and can't now after installing Dx10, that could be the problem.
BTW, have you tried other games, either online only or otherwise, to see if the problem is just with GW? That may help...
