Everytime i start up Limewire i get this

"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 to access the internet and restart limewire"

What does all this mean and how do i fix it?

Well...you need to unblock if from whatever firewall you are using.

For windows firewall just go to start>control pannel>Security Center>Windows Firewall>Exceptions..and add Limewire to the exceptions list.

You can try that but I think it is probably another firewall you have, there is a post somewhere about this...sorry don't remmeber.
