Trouble lunching LW

[Commanderkeen]

When i click on lime wire 2 start it it comes up with the message "Limewire was unable to initialize and start. this is usally due to a firewall blocking limewires access
to the internet or loopback connections on the local machine. Please allow Limewire access to the internet and restart lime wire."

I turned all my firewalls off but still nothing

Any suggestions
