Can't Connect

[winditup123]

Hello. I've been having some problems with connecting limewire. I have used it for a long time now and it always worked fine, buy suddenly, a few weeks ago, it just stopped working. I can't connect to the network. I start up limewire, everything seems fine and then it never gives any results when I put a search. The connection bar is at the lowest and the firewall symbol seems to be blocked. I tried fixing the firewall, giving Limewire access, but it already does have access, so I'm not to sure what the problem is. I'm not sure of the answers to the questions, but I know that the computer is Windows XP and the firewall is Zone Alarm. Any help will be greatly appreceated.
