Try going to your connections Tab in limewire, if it's not showing up go to Veiw > Show/Hide and make sure the connection tab has a tick next to it...
Then click on the Hosts and remove them and let Limewire search for some more...
Also make sure you have replaced the port number that you selected when you port forwarded and place it back into the manual port forward box and the listen port box and select apply...
Another thing to look at as well is AT&T they are known for shaping p2p connections...
