Can't start any game, prompts for password

[anelson]

I purchased the game today. The installer runs and checks the key I give it from what I was emailed and says it seems okay. When I try and start a game I get prompted for the password and when I enter what I have been emailed it just goes back to a row of 0's. I installed on an Ubuntu 8.04 Laptop with 4GB of ram and a dual core 2.4 Ghz CPU.
Any thoughts?

Thanks
