I'm having a bit of trouble with the Illithium Quest. With it installed, my game refuses to load the Copper Coronet. When I try to enter, the game autosaves, then starts to load the new area. Halfway through loading, I get an "error" sound, and the screen goes black. Windows figures BGII "fails to respond". Without the Illithium Quest, everything works fine. Never had this problem before, though I've played through this quest a few times.
