Hello, I have exactly the same set-up, with ZoneAlarm listing Limewire very clearly as exception. I ran through everything suggested in the other thread about replacing the gnutella file, reinstalling, etc.

But:-

After about an hour I realised that my new router also had a built in firewall and by lowering that I was able to connect instantly.

I don't know what router you had, but mine stated something like "allow p2p gaming and uploads, etc" which wasn't selected.

I hope that may be of some help to you?
