Behind a firewall?
 

I just installed LimeWire maybe 2-3 weeks ago, and it worked just fine! A few days later I started to get this message that told me that I was behind a firewall and that LimeWire couldn't connect to the internet. I just ignored that and just kept pressing connect again. I later checked my firewall settings and it said that LimeWire and it's installer were allowed full access to the internet. Now when I try and connect to LimeWire is just won't connect. I'm not sure what's going on and I've ran virus scans to make sure I haven't picked up anything.
