Just Turn it off temporary, Try a few different port No's till one works
Try manual port faward.
Both Listen on port & manual port faward, should be the same in Limewire
Tools/options/Firewall Config. Do not forget to Apply.
When one works you can then add that port to XP exeptions n turn it back on.
Oh!! Leave Limewire to settle after changing ports 15 mins or so
Good Luck
