go
here to re-download the binkw32.dll. Find that same file in your game install directory and replace (overwrite) it with the one you download.
If that doesnt work then reinstall the game again.
If that doesnt work then you more than likely have an illegal version of the game!!
If you do indeed have an original purchased version of the game then contact the games technical support!
And wrong forum, moved to 'General Gaming' Forum.
