"Limewire is currently connecting to the network. Your search may not return until you are fully connected to the network."

This pop up always keeps popping up even after a few hours. There's only one green block out of the five, with the wall of bricks. When I search for something, the page is just blank. The Limewire sign thing just kind of keeps on spinning.

This is my first time using it on this computer. It works on my brother's computer, but it doesn't work on mine?

Help, please? Thank you for helping.
