Limewire and CCProxy

[conundrum]

Hi everyone, this is my first post so please be gentle with me

I have a small wireless network running at home, which consists of a broadband connected PC and three wireless laptops, all running Windows XP. I'm using CCproxy on the main PC to share the broadband connection, and everything is fine. Everyone can connect to the net and browse and use e-mail, but I've run into a problem trying to get Limewire to work on the wireless laptops. The main PC works fine, but on opening Limewire on the laptops it never manages to connect. It just sits on the opening screen, I get:
Quality: Connecting

and it never does.

Anybody ever had this problem? And if so, how did you get round it?
