XP has a build in firewall:

Try to disable both firewalls, only to be see if they are causing the problem or not.
Did you remember if you changed anything (not only within Limewire also XP, firewall)? Did you install any other programs short between the time Liewire worked and didnīt work anymore? Do try to connect from home or from work? Are you within a LAN? Do you have a router?
