It sound crazy, but there is a very simple solution to this. Basically, open up your explorer and click on "Libraries" on the left side menu. Now you should see the four links on your right. Hightlight them and delete them away.
Oops, all gone. Do not worry, the content is safe. It just remove the link away. Now highlight "Libraries" on the left again and right click. Select "Restore Default Libraries".
Thats all to it. Restore any other links in your libraries if you have them.
