Connection Problem
 

I have had limewire for sometime now and it work properly for at least four months, then all of a sudden limewire said it detects a firewall. It's connection is only on one green line. All my firewall settings are off on my computer, wireless router and internet router. I use Mac OSX 10.4.11. Does anyone have any advice on what to do. I haven't changed any settings since it was working and it suddenly stopped.
