Well, I re-uploaded the file that was "missing" after I had done the complete deletion process and re-uploaded the module, and uploaded that file after rebooting, and was able to turn on the link manager sidebox in my WAMP test server.

However, the problem of duplicate descriptions and title remains.

The only place where that information is entered is in the admin->layout boxes controller. If I find the answer, I will post.
