Ui_interface error Ubuntu 10.04

[paulchain]

I am using Ubuntu 10.04 with an ATI 4650 1gb Video card. I have the correct drivers and yes 3d acceleration is working because I can even play world of warcraft fine. When I start the game I get that pesky UI_Interface error. Everybody keeps saying "The server maybe down" but unless this game is dead, there is no way the server can be down for over 2 weeks now. Does anyone know how to fix this?

The server maybe down...

...just kidding xD

Are you behind any firewall or proxy?
Can you take a screemshot of the error message?

[paulchain]

No firewalls or Proxy

Here is a copy of my screen.

Have you tried connecting to both RA and Horus?
Can you ping 91.123.197.141?

[paulchain]

Yes both servers cause the exact same problem. Yes I can ping that address, it has a latency around 192-194.

What is the output of this?
nmap 91.123.197.141 -p 48000

nMap shows this...
