operating Limewire on a LAN network
 

I've been trying to get limewire to work on my iBook (OSX 10.1.2) with no success. Think it might be because I'm linked up via a university network to the net (LAN). Anyone know how I can get it to connect? What I can't understand is that I'm getting ads at the foot of the window so, theoretically, i should be connected but I can't accesss anything in the "services" window and the "search" button isn't highlighted. Also, shouldn't I have to sign in every time I open up limewire?

anyone with any ideas please help- these graphics are to cool to waste!
