the bugserver at http://bugreports.limewire.com/bugs/home.jsp has been down quite a bit recently, and you don't get a personal reply from it when a bug report is accepted.

Re the corruption--try using the latest version of LimeWire from www.limewire.com to avoid one of the modified versions that are out there. However, I suspect you already tried that and need to look at the stickies to remove all traces of LW and clean up any chance you got a virus.

Sounds like you should also clear all your old downloads quit LimeWire, and delete the Incomplete Folder to start fresh.
