If you have one of the newer versions of the game, back up your game save before uninstalling it, then uninstall it and download the latest version. However, if you have an older version of the game and want to update it, you will have to start playing it again, as older game saves do not work properly in newer versions.If I delete the game and re-download it, all my save data will be lost, and then I'll have to start all over again?
