Hi all,
I have tried everything suggested in this forum.

What DID work was checking my routers firewall.
If you have a 2wire wireless router/firewall, login to the "Firewall/Advanced Settings" menu and ensure that you have the "Outbound" controls for "All other protocols" and/or "IRC" checked.

This may be blocking the Limewire in/out ports.

Hope this helps.
