Yeah, no idea. I dont know how I got mine to get past it. But it works perfectly.Yeah sadly still no luck with the game save either. I even went ahead with your other suggested steps and uninstalled everything, did a restarted the system, did a full install of a different version which came out to 31.4gb (base+update+26dlc), loaded up the game save, start up the game and runs right into the updating game data and stuck there.
@ForgotWhoIam - Not sure if that does anything to it. I have always had mine as FAT32. I read about exFAT causing Issues, and the Card even becoming Corrupted. So I stuck with FAT32.
