Your Favorites folder is probably corrupted. See this site for instructions
on how to delete that folder - it will be recreated as empty when you
reboot, then reimport your Favorites to the new folder: http://inetexplorer.mvps.org/answers3.htm#favorites
If you are using WinXP, you'll have to delete that folder from another
account with Admin privileges.
