It's extremely unlikely that your game progress will be gone. That's stored on the game server, and accessed through your ID and password. Even if you delete and re-install the game, you should be fine. If you go to another game device and log in with your ID and password, your game progress should be there. The only way you can lose your progress (assuming that the servers themselves haven't failed, with all of their backups!) is if you're playing "anonymously". In that case, it's very difficult for the BBB support people to reattach your game progress to your device.
