Check if scp-294.ini exists on your Data folder. Try unzipping your SCP:CB download once again to get it if it's not there, or if it's there do so anyway to replace the game files. If it still fails, redownload the game, and if that still fails, try compatibility mode on Windows 7 and/or with admin rights and try again.
