Frozen game, corrupt data

Sorry I think you don't actually need to create a corrupt file to get the 800 points, you just need to create a new save.

So if you've already got a working non-corrupt save then you need to get rid of it, so go to your Storage device in your console settings and delete the existing save, then when you create a new save you should get the 800 points.

Which sucks for anyone that has a working save and doesn't want to delete it just to get the 800 points, even though we deserve those points since we lost our teams from the corruption.
