I have tried port forwarding. I have disabled the Linksys firewall, and enabled the McAfee Firewall. I have enabled the Linksys firewall and disabled McAfee Firewall. (Windows Firewall always is off.) I always have the brick wall icon, and when I click "Connect" (on LimeWire), I always see "Starting Connection," and one bar. I have left LimeWire open for [seemingly] forever, and still no connection. Before upgrading to LimeWire Pro, I had LimeWire,, and all worked fine. Then I upgraded to latest McAfee Security Center when I got a new computer, and have been entirely unable to connect since. I have configured the ports on McAfee Firewall, and the program permissions lists LimeWireWin as "Full Access." Does anyone have any suggestions?
