Please Help Me! Firewall Issues!

[oxcr1stalxo]

im not very good with computers, but i have windows XP and have only one firewall ( the windows XP firewall) when i installed limewire pro, i was asked to either "unblock" or "keep blocking" i choose "keep blocking" then realized that my firewall blocked limewire and i was unable to connect, i added port 6346 to my exeptions list under my firewall options and i also added IP 127.0.0.1. and even added the limewire program and it still says that i have a detected firewall and there is a small icon of a world and a brick wall infront of it when i run limewire. Im pretty sure i can connect to the gnutella network but not positive. i was able to connect to ares, kazaa, and morpheus. i tried completley uninstalling and reinstalling but it never asked me again to "unblock" or "keep blocking" i really love limewire and hope that i can connect, thanks for your help.

ps. im connected through ethernet from my apartment. and have norton antivirus but not a norton personal firewall.
