Whenever I click on the limewire icon, located on my desktop, this is the message I receive:

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 to the local machine. Please allow Limewire to access the internet and restart Limewire...

I read this and so I go to my firewall program area and place an exception on limewire that is suppose to allow it to access the internet. Problem is, it doesn't do anything and it still wont't start. Can someone please help me because I'm getting very frustrated?
