At points in the game I keep getting errors.
This always happens during battles and always around the same moment.
So far I only get these errors during fellowship campaign but it's still annoying because it means i cant use the dwarf quests or defend Ithililen(I hope i managed to spell that right).

Has anyone else had any similar problems.

I just want to know if this is a game issue or a system issue(playing the game on a 32-bit windows vista).
