I have BOTW installed on a 32 GB USB drive, its the only thing in the drive. during game play I only had one or two crashes but when the game plays one of the memories movies I get a USB error screen. Now it's happening with the ending movie so I can't get to have the game finished. Can I just reinstall a new downloaded version of the game in the same USB? Do I have to back up the save or it will be OK?
