I am having trouble connecting. I've just installed limewire and I tried to search for an artist and clicked on ok. Then a little message pops 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 am currently on a network at home (connected to one modem) and there are currently 2 other computers connected to the home network.
I've tried installing and uninstalling limewire to retry and the same problem comes up. The bar at the bottom left hand corner only has one green bar and the rest are all red. I have a globe behind a wall. I'm guessing this is the fire wall.

Whats the problem??
