Limewire used to work perfectly but not it only gets one bar. PLEASE HELP ME!!!!

[kowchpotato]

ive been using limewire for about six months without any trouble then one day it wouldnt connect. it just continually says its connecting but it never goes past one bar. ive tried addind it to my computers firewall as well as mcafees firewall. nothing happened so i tried turning both of them off and still nothing happened. ive also tried adding ports to the firewalls. another thing i tried was port forwarding but i got to the part when you have to put the ip address into the address bar on your web browser and an aol with google search page came up and said it was a bad request. if you can help me from here that would be great.
