ive been getting that for the last few days. given up!

downloaded frostwire and that was exactly the same. but on their forum they suggested opening the connections tab
Lime Wire » Connections to see tab

and adding
82.34.136.17 port 29534
and 201.68.243.31 port 26048
hey presto magically all bars lit up.
cant be bothered to go back to limewire now. but it might be worth a try
