Satellite Broadband Connection UK...Help needed!

Basically, we have Aramiska Satellite Broadband in our offices, Limewire worked fine on two machines for about 1 hour and then gave up and has not worked since...

In the bottom left corner it just always says 'connecting' and never changes from that...any ideas????

cheers in advance if you can help!

We are using Mac OSX 10.3.4 and the firewall software is called squid and we are through a router......
