i have tried everything that has been recommended on this topic, but nothing works. My brother has limewire on his laptop as well and neither of our limewire's are running. I have AVG free and that does not have a firewall and the windows firewall was configured to allow limewire, but limewire has refused to work for the last few months. Is it possible that there is a setting on the main computer of the wireless network or is there something else i could try?
