Limewire was working for the last several months, but now, can't make a connection. Connection status just shows "connecting....". Using Windows XP pro, SP2; virus protection is Avast, there is no "exceptions" option but I have tried listing "...LimeWire.exe" as an "exclusion" from scanning. Windows firewall is off; I have a wireless router, but no settings have been changed since when Limewire was wrking.
