My game won't start!!!

[Phineas]

Bought the game via Direct2Drive digital download, and it seems to install and set up ok. However, when I actually try to run it, it appears to launch something, but I never get into any game menu. It merely stops after a while. In task manager, "kb.exe" is running, apparently, but there's no way for me to get into the game. I end up shutting down kb.exe manually. I am running Vista-32 with a 8800 GTX and I have tried with user account controls enabled and disabled....same problem. Also have tried running in XP compatibility mode, and am running as an admin. Same problems.

Please help!
