Make sure you've only got 1 firewall running & that it's set up for LW to work. If your router uses UPnP, turn it on in the router & within LW (tools > options > advanced > firewall config > use UPnP & apply).

Do the port test & see what result you get.

*If the XP firewall is the only one you have, better to turn it on & configure it for LW than to run without a firewall!!
