I have been downloading on limewire forever, all of a sudden last week my firewall wont allow any searches,nothing! I have reconfigured my firewall settings in windows and my one care security with microsoft. Still nothing. I have also checked my firewall sttings in limewire. Limewire is listed in my allowable sites for my firewall settings but still nothing. Very upset!!! I miss my limewire. HELP!!!

You only need one firewall !!! More than one will cause problems.
Make sure only one is active & properly configured. Try removing the firewall exception for LW & then re-adding it.

And is still no work:
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.)
