7dbv19bx8glx When the game does that, it means that the game cannot open the save. IOW, the save is now corrupt. The best you can do is to try to recover an earlier version of that save. So, use Load, mouse over to the top listing and next to the delete button. There should be a recover button there. Click the recover button and a list of the versions of the save that are available will come up to choose from. Select the top one. Let the save file create then try to run that. If it doesn't work, then try again with the next on the recovery list. You can do this up to 5 times if the saves are available. If none work, then you can try to play an older save (or recover). If none of that works, you'll have to start a new save.
Hope this helps.
