Sounds like your firewall or your modem is not allowing you to connect thru port 6346.

*** Your AVG windows free version is an anti-virus program right? This is not a firewall but some anti virus programs can affect things if it is not configured to allow LW access. I don't know about how to set yours up. It seems you 'should' have your XP firewall active after all. I misundertood when you put AVG next to the firewall question.

LW has the ability to utilise devices that use UPnP so it will automatically open a port for LW. But if your device doesn't use Universal Plug and Play (UPnP) then port forwarding may be required. I somehow suspect you don't have the ability to do this.

You didn't answer some of my questions in my previous 2 posts so I'm a bit in the dark at present.

Did you delete the LW preferences as suggested?
