I started the campaign got past the save point and was unable to mount the truck as no icon appeared. I exited the game and started it again hoping to revert to he save point. I was told that i couldn't play or edit as i required downloadable content that was now deleted. I then tried running a Showcase from the begining saving it coming out and trying to revert to the saved point. It wouldn't allow me to. I got the same message. This used to work fine.
