Very kind comment! :-)
If you can run LimeWire (pro or otherwise), as far as I can see it must be installed correctly. From there on it is a matter of having your Internet access set up correctly. If your 'Net access is via a LAN, as is mine at work, then you may well be sitting behind a firewall. Unless your network administrator allows access through port 6346 (the port used by default in LimeWire's Options/Advanced/Port panel) then I'm afraid LimeWire simply won't be allowed to communicate with the outside world from there.
I have this problem at work, and it means I simply can't use LimeWire there. Fortunately I have DSL at home... dynamic IP address, but not such a restrictive security setup.

Hope this helps - gotta run
