Game Freeze, The game freezes up while I'm playing GRAW 1 in Hard Campaign mode Options

[nojevolnam]

I've been playing GRAW 1 for awhile now and made it through all of the missions in the normal campaign mode. I just started going through the hard campaign mode and the game has frozen up 3 times now. All 3 times I have been unable to go back and load the saved campaign. I click on it and hit play and the machine just cycles. It looks like its going to launch but never makes it and I have to shut my xbox down.

Anybody else had this problem and if so what'd you do to fix it?

Thanks,
