Game won't start (Problem solved)

[David]

Upon trying to start the game (clicking Play in Steam Library)
LoadLibrary failed with error 193: 1% is not a valid Win32 application.

Upon validating with Steam:
1 file has failed to be validated and will be reacquired.
(and always fails to be validated after the reinstalling Python step)

After that, upon restarting Python tries to install again.

Same error if I delete all local content and reinstall from scratch from Steam.

Getting these errors after reinstalling python and restarting Steam- basically can't even load the game. Any ideas?
(edit: Windows 7)

///additional error if I try to run in WinXP SP2/3 compatibility mode with run as Admin///
after double-checking, I only get this additional error when trying to run damned.exe directly from inside the folder (outside of Steam and desktop shortcut)
"windows system32 atioglxx.dll is either not designed to run on Windows or it contains an error."

Thanks, it was the .dll after all then. Acquired a new one with this.
