Same problem here... but wait there's more...

Now my backup drive (external) shows up twice, libraries which was previously hidden and all the crap folders it contained, which were previously deleted, are now all back. All the folder checks, as suggested above, are checked. There is no way to just Hide Libraries by right clicking on it. Show Library is unchecked.

I've run the regedit actions that previously were published on this site to delete them, but they no longer work. My registration files are properly coded.

Any of you gurus able to help?
