bfme2 lord the rings battle middle earth ii

I can't get this game to run in Vista B2. The game will load up and if I change any of the options (like Extreme Detail to High Detail) or try to go into a multiplayer game I get kicked out with a Game Crash message and something about Direct3d. I have a Nvidia GTX7800. Is this just because the game isn't compatible with Vista or is it because there isn't a good Nvidia driver for Vista or Directx10, possibly?

Me too I install bfme2 and it fonction perfectly. I don't think it's because directx10 is not compatible.
