I seem to be having the same problem. Over the past few weeks, Limewire has been sporadically not connecting on me, and yesterday and today it will not connect at all. Why would it connect some times and not others? Here's what confuses me even more. I have a second computer which runs XP (the one I'm experiencing problems on uses Vista). The XP machine, which has Norton installed, connects just fine. My Vista machine, with McAfee installed, is the one having the sporadic problems. The two computers share the same internet connection through a wireless router.

I am really at wits end here. I have tried every fix in that link. I have disabled McAfee's firewall, uninstalled the Firewall, closed down McAfee altogether, kept Windows firewall off, installed the latest version of Limewire, and still won't connect!!

Here are my system details:
