well, mine started working today finally. I didn't do anything to it, so I have no idea what the problem was, but w/e.

Anyone have any ideas? I haven't been able to connect to Limewire since then.

If you're sure you're not running more than 1 software firewall, & you've configured the Windows firewall properly
Firewall setup
then you might have to look at an internal firewall within your router. Have a look through the thread below, it has lots of info about connection problems.
Connection problems? Check here first!

If your router supports UPnP, try enabling it & then choose the 'use UPnP' option within LW's tools > options > advanced > firewall config. If using UPnP doesn't help then try manually port forwarding. Find your router at this site & follow the directions (don't forget to set up a static IP first, if you're prompted to)

See how that all goes

Thank you very much, I had already tried the things listed in the first and second post, but the third post helped me.
Limewire is currently working, I just hope it stays working this time.
If it does stop working, I'll post back here.
Again, thank you very much for your help.
