That's right! The multiplayer doesn't work. The Solo Game thing works, but not the Server mode. It just says Getting Info on Servers... forever. I want to play online and show my sabering skills! Boo Hoo!
Up at the top there's an option to that says either Local, Favorites or Internet. Select internet and see if that works.
Disable firewall software like ZoneAlarm.
Sounds like a common problem (firewalls not configured properly).
You can also open ports 29060-29099 UDP & TCP if you must run a firewall while playing/hosting.
