'Can't connect' Limewire PRO to OSX 10.2.8

[jdauel]

My LimeWire used to always work with my computer before I moved it. Since I couldn't get it to work, I ended up buying Limewire PRO because I figured they might not be supporting all the free/basic versions as well anymore.

Anyways, here's the error message I get when I try to run Limewire:
"Your machine does not appear to have an active Internet connection or a firewall is blocking LimeWire from accessing the internet. LimeWire will automatically keep trying to connect you to the network unless you select 'Disconnect' from the File menu."

I've read that I need to port forward (or) manually configure the firewall. Problem is, I haven't found anywhere that gives me any advice for macs or my specific router. I have a DSL connection through the SpeedStream 5200.

Can somebody help me out? LimeWire's support sure isn't getting back to me...
