Limewire won't connect to the internet? :(?

I've had Limewire for maybe two years and today it isn't connecting to the internet. Last night I used it and it was working perfectly- but when I tried today all my downloads "Needs more sources". Then it told me to go to File > Connect. So I did, and it has been 'connecting' for over an hour. Its not working. I have Windows XP, and all of the bars are red except the little one which is green, and when I hover it says You are currently connecting to the network.
I tried turning off my firewall and try downloading but its not working either.

Thanks for any help in advance!!
