I am asking this on behalf of a friend....had the problem myself, but I can't remember how I fixed it. When using Internet Explorer, if one goes to tools/options, you should be able to delete history,files and cookies. Try as hard as you like, some files will just not disappear. If I go to Control Panel , Internet and attempt to delete from there, same problem.
I had the answer some time ago, but unable to remember how I did it.
