Lungfishopolis: crash with 0xc0000005 error
I've been enjoying playing Psychonauts (PC), but now all the fun is on hold as I have a game-breaking crash in Lungfishopolis.
Right at the beginning of the level, after freeing the 3 prisoners and getting my shield badge, I walk a few steps down the road and get a black screen. I alt-tab out, and get a dialog box saying there has been an error at 0xc0000005. This happens every time. I have tried restarting the level and exiting to the real world and coming back through the brain tumbler but with the same results.
My machine's specs: P4 2.8Ghz, IGb RAM, OS XP pro SP2.
Video card: GeForce 7800 GS (AGP): ForceWare 93.71 drivers.
The game is patched to 1.04.
Any advice would be much appreciated!
