We have XP with no active anti virus or spyware. We have turned off the firewall and added Guntella as an exception for both TCP and UDP. We have contacted Roadrunner who says they see no firewall in the router or modem an they do not block peer to peer contact. They do throttle them. They can ping us. Anyone know what we should try next? We have downloaded Limewire a half dozen tiomes already. Any help would be appreciated. THANKS in advance!
