Very odd.

A few questions, then:
  • What exactly are the errors, and when do they occur (both in game terms, and real terms)?
  • Did you follow the arduous install procedure for nvidia drivers on vista correctly (ten million restarts and all that )?
  • Have you installed dx9 manually?


Can't think of much more for now; if I do think of anything/when you get back, I'll try my best
