Please help a n00b out. (not connected)

[biglouT21]

i downloaded limewire recently and the night i downloaded it it had worked fine i even got some songs but the next day i wasn't able to search for anything and everytime i tried a message came up saying "limewire is currently connecting to the network. Your search may not return many results until you are fully connected to the network." i left it alone for a couple hours thinking it would connect but it hadn't and i'm pretty sure it isn't my firewall since i had reached the point of simply turning it off when i tried to do something. Please help i've been tearing this thing apart and i still don't know what to do. I'm sure it has something to do with the bars being red and not connecting but i don't know how i can improve or even establish a connection.T-T
