Crash on game exit

Every time I exit my game using "Exit;" I get the standard Windows warning "Acknex has encountered a problem and needs to close. We are sorry for the inconvenience." And then it has the two buttons giving you the option to send or not send an error report to Microsoft. I was hoping it was something that only happened when running the game through WED, but I've now done the "publish" thing and I still get the same crash. Any ideas?

Nevermind. I found my problem. I wasn't deactivating some dlls before the exit.
