I'm not quite sure what happened. Just one day, Limewire would no longer connect. It says I have my Firewall set to block it, but i have Limewire.exe, the installation file, and javaw.exe all set to allow full access. Limewire also says this when I turn the firewall completely off. My firewall is a McAfee, and I'm not using Windows firewall with it. I've tried deleting the .limewire folder in my Documents and Settings folder, and also reinstalling. Here are some specs, I don't know if they'll help.

Windows XP
512 MB DDR400 RAM
McAfee firewall

I also tried clicking on the test page thing that I saw in another link, and it said the test worked. Please, if anybody can, help!
