Have you tried looking for the answer yourself in the last TWENTY HOURS?
You have a firewall somewhere that is messing with things (hence the brick wall in front of the globe). I would recommend port-forwarding your router, as it may have an internal firewall. Go to port-forward.com, and click on port-forwarding. Select your router from the list and then select Limewire. Instructions will follow.
Let us know if you have luck. If not, further suggestions can be made. Try reading the stickies at the top of each of the subforums. They have tons of useful information, including the information that I just provided for you.
Good Luck
