Sometimes my crashes say they cant load some textures. I saw that two times now, with one of that samurai-armors and some russian-/khergit-armor... if i remember right.
usually i cant see the error, because the game freezes and is on top of the screen, while the error is in the background. if i press [Enter] or [Space] now, game and error vanish (since i press "Okay").
I think reinstalling windows could work. But that would be a pain in the ass, since i dont have an empty HDD for backing up the stuff on C: (that I would need.). Also, it seems to be a game-problem, so I would not go that far now.
