I have the same problem: I have a folder I can't delete, it says access denied (I put it inside another folder, and when I try to delete THAT folder it says "wrong parameter." I tried restarting in safe mode, and when I do, although I am an administrator, my profile is not in the list. So i signed in under the one that does say "administrator" and even though the folder shows when I drill down through directories, when I right click the folder it says it can't be found! There seems no way I can get rid of this D*MN FOLDER!!! Help, please!!!
