Everytime i try to download a song, i get an error message saying there has been and internal error, and that limewire can recover from it, then when i click ok, the song says could not move to library. What do i do?

You can copy and send the error to bugs@limewire.com (if it wasn't set to send automatically) for starts. The automated reply would probably recommend reinstalling LW. In addition, cleaning out the old incompletes should help. "Could not move to library" messages should be pretty rare, unless the save folder is "protected" somehow.

If that doesn't help, post back with your LW and OS version.

Cheers
