I got it to work. I was using an aircard. Not a modem/router. Or if in the net world those are considered the same thing, I'm sorry.

I completely uninstalled L/W then reinstalled using the latest version. But now, everytime I want to connect, I have to completely erase the .limewire folder (I had tried it before, but it didn't work. When I got the new L/W then it work) then start and use L/W. I have to do this everytime I want to use it. But when I do that, all works fine.

Thanks for the help folks!
