I was having a problem with my firewall. Even though it wasn't actually running it was still blocking access to the servers.
I wasn't able to get it to allow access so I uninstalled it. Limewire started working immediately after I did that and I reinstalled the firewall. Everything works fine now.
Try all - try anything
