The TRUE result is very good news!

Your PC-cillin(antivirus) I will leave alone for the moment. Never heard of it & at this very moment am too tired to research it (perhaps tomorrow if you're still having problems.) Your XP firewall see here: http://www.limewire.com/english/content/firewalls.shtml to ensure LW AND Java have full access.

SP2 could be an issue. It has been for a great many businesses & p2p users. But we'll see. If you search sp2 on the forum you'll find plenty of feerences to it as well as patches for it (both by M$ & 3rd party.) SP2 changes your firewall settings back to default & also limits your connectivity to the net.
