Gnutella Forums - Shared Files are disappearing

Several times in the past month or so, all shared files have disappeared! Both of my kids and I have downloaded songs, and have played them. When I attempted to play one this morning, I get that C:\Program Files\Limewire\Shared could not be found (the shared folder is there, it is just empty). I use Music Match Jukebox to play/organize my downloaded music.

I know that noone physically deleted the files. Anyone know what happened to my music? CDs that I have burned are still in mmjb, just limewire songs are gone.
