I've just installed LimeWire 4.10.3, and I keep getting this message when I try to open it: Limewire was unable to initialize and start. This is usually due to a firewall program
blocking LimeWire's access to the internet or loopback connections on the local
machine. Please allow LimeWire access to the internet and restart LimeWire. Then it closes.

I've turned off my firewall and added LimeWire to the exceptions, even upgraded to LimeWire 4.10.4, and I still get that message, what am I doing wrong?
