Yes I did burn the image to a backup DVD.
Is there another way to play the game??? Edit: Ooops! Grid can play from a mounted image! Amazing. I still prefer the backup solution though. Trying to find if DeamonTools will burn that image for me? Can I use Nero to burn that image if it does not?
BTW I used Daemon Tools to make an image of Grid and it took more than 1.5 hours.
