It is the order in which I was doing it. Need to delete game. Then go into Setting, game centre and log out. Then log back in again. Then open Bakery Story, look at the top right hand drop down box, choose Restaurant Story, click install. This took me to apple store, when I hit the download cloud.
Then, wonder of wonders, it gave me the choose to continue the basic level it had given me this morning or ...., and here comes the wonderful bit, all my old game stuff was there, just waiting for me. I clicked on it and ta da! Yippee! Doing happy dance. Thanks everyone!!
Thanks for such simple instructions. I?ve followed them but am still not getting my level 99 restaurant.
