I downloaded it and it all seemed fine but when I try to run it it comes up with this messge :

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.

I checked my firewall settings and it isn't blocking Limewire, what else could be the problem?
