I'm hopeful we'll be able to work through this. Like Marc said, it seems to affect some people but not others, which makes some sort of conflict suspicious. I took a few minutes this morning and tried everything listed in the earlier threads about this, and I can't get the damn thing to crash.
It would be great if you could get Marc the saved game. It will be very telling to find out if the same game crashes on one of the "non-crashy" computers.
Thanks for your patience, everyone.
