FE.DLL???????????? HELP!!!!!!!!

All of a sudden the other I was about to play the Crusaders campaign when I got a Windows error that said it would have to shut down CFS. In the details it something about FE.DLL. I did a little experimenting (Yeah Right, a little) and found out it only happens when I add a campaign or mission to CFS. Its always worked fine until now. I've never had a problem with add-on Campaigns or missions. Does anybody have any idea what FE.DLL does or why my campaigns and missions all of a sudden won't work? PLEASE HELP
