Two years ago pro support was only for 6 months. A year & half ago they introduced a 12 month option for support. Once that period is reached, your email addy on their systems is auto removed. Oh ... from time to time LW do offer a one time Pro with no pro support or updates.

You still have the Pro installer right?

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

Delete your previous LW Preferences folder before you reinstall LW; instructions here: Point #3 in Fixes for Limewire (sample image included at bottom of page.) or if using Vista, see http://www.gnutellaforums.com/genera...der-vista.html

BTW I'd suggest using both of those system cleaners suggested.
