You ever played daggerfall? now theres a bugged game. anyway, i would try restarting the game from sctratch. you might want to try re-installing the game first though, it is probably easier.

From the error message id guess that something about one of your characters has been corrupted beyond the games ability to recover.

You might also want to use ShadowKeeper to examine your chracters and see if theres anything weird in their, although youd have to know a fair amount of the infinity engine to determine if something is an error or wierd but correct.
