Greetings.

I'm having trouble getting my purchased version of LimeWire to work. I suspect the problem is a firewall--from my router, cable, or what came with my new computer (Mac OS 10.2), I don't know.
So far, it seems that the router is most likely suspect, however, tech support told me I need to get port numbers from the company that designed the application/service I'm trying to use. No one from LimeWire has answered my questions.
Since I've never used a router--or a firewall--at home before, is there a given port number? The LimeWire FAQ mentions "6346" for Gnutella but I gave that a shot and it made no difference.
I'm able to download maybe one in every thirty files I search for. It seems no one is able to get to my files at all. Any helpful advice would be greatly appreciated.

Thank you!
