If you can help out please....

I just downloaded Limewire 4.9.11 I opened it and put the firewall settings in they require. I tried to search and it keeps telling me something about no connection possibly due to a firewall. I turned off my firewall and it still will not work....any ideas?

I am using Windows XP and Norton Antiu Virus 2004 with all the updates on both...?

Please help...any and all information in greatly appreciated.
