i did what you said to and still the same error message pops up. Initially, when I installed and used the Basic version(an older version than what is posted now) of Limewire, it worked fine with no errors. This all started when I purchased and upgraded to Pro version 4.12.06. I then tried to unistall and reinstall the Basic to see if that would work and it did not. Of course, the basic version was now version 4.12.06 and not the original one I was using. I have read other post and tried to configure the Gnutella service for port 6346 for both UDP and TCP. I am not sure if this is the right port but I chose it anyways. I have also tried to disable norton anivirus and its firewall options and also windows firewall. Again, it did not work. Got any other suggestions?
