I have not been able to get this working at all, tried it as an admin, or to set compatibility as all Windows versions. My OS is a Windows 7 Professional. I've managed to run it using -console (via shortcut target).

Does anyone know what the issue is? I downloaded this clean from Steam (with Condition Zero) and it won't work. Everything inside the game is fine.
