How did you try to uninstall it? If you used the control panel -> install/uninstall programs that is the incorrect way.

Normal way is Start menu -> All Programs -> LW -> Uninstall.

Try this: http://www.gnutellaforums.com/333278-post2.html, however use your Pro installer instead.

Also, delete your previous LW preferences folder before you reinstall: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.) or for vista see http://www.gnutellaforums.com/genera...der-vista.html
