Also check to see that after re-installing LW, that your browser hasn't somehow become blocked from that site or that LW needs clearance thru your firewall again. Some AV programs such as Norton require you to reset LW configuration thru firewall if you have reinstalled LW. eg: Reconfiguring Norton Firewall

If resetting or clearing & re-doing the firewall settings to allow LW full access doesn't have any effect, then try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)
