Take your GT5 disk to the side and make sure no-one else is around.
Tell it to sit down...and explain that your down to your last resort with it. You've tried everything to make things better, but it still disobeys you.
Tell it that if it doesn't get it's act together, you'll have to pack it's bags. Tell it you don't want this to happen - you love him - but you're down to your knees.
It used to get on so well with you, but after those things happened it's never been the same. Tell it you can change, as long as it's willing to contribute as well.
Give it a pat on the back and a smile. And as you both walk back together, tell him "one more chance".
