Thank a lot. But can you give me a picture how to do it ? I delete the game already but not download yet. Thank you.
Make sure to set and save a transfer code/ID through the help/settings menu to save your progress. Uninstall/delete the app. Download and install the new mod for the new version on the first page of this thread. Open the game, choose "Continue game" when it asks, and enter your transfer code and password you set earlier. Let the game download all the data and you are ready to play.
If you didn't set a transfer code or connect a Facebook or Google account before deleting, your game progress is gone unless you saved/remember your UID from the top left hand corner of the screen, in which case you can recover your account using customer support in the app.
If you want to start a new game, the only difference is when you get to the 2 buttons asking to start a new game or continue? Press new game and start from the beginning.
