I can't remember ever hearing of AVG causing a problem with LW. That doesn't mean it couldn't happen. AVG's an anti virus and shouldn't be blocking ports. I tend to think it's your firewall.

See: Firewall configuration instructions (click on link).

Most routers have an internal nat firewall in them. If it doesn't support UPnP, you'll need to port forward it. Find you router here: PortForward.com - Free Help Setting up Your Router or Firewall

Well, thank you for your help. For some reason now, LimeWire will connect. Sometimes it will not, even when the circumstances are the exact same as the last time that it connected. However, my point being is that it will connect right now. Thank you!
