Problems with a Wireless ISP
 

So I just moved into my new apartment and am using the apartments ISP, SilverIP. I am having problems getting my Limewire to connect... I think it may have something to do with the fact that I have to sign myself into my service each time I boot up the computer... Limewire seems to think it is a firewall, which could be the case. I've tried doing some Proxy stuff, but it's really not working at all. I'm running Mac OS-X 10.4.2... anybody have any suggestions or am I just screwed...
