Hello All I am a new member here today !!! I have recently purchased a laptop and bought this game online dvd version that has arrived today. I have installed it and patched it to latest version. After a little trouble with a missing directx file I ran the game....only for it to say : media verification error: The media could not be verified to be a valid original. Please insert the original and try again. I have tried disabling Norton anti virus and other processes but no joy. Any ideas would be greatly appreciated...I am dying to get this game going...It looks amazing Many thanks
