[How-To's are under the Topic]
I had the Same Problem with the FULL and LITE Version.All you have to do is,on the iPod/iPhone,delete the App.Then,go to the App Store on the iPod/iPhone,find the App,and re-buy/Download it.If you bought it,it WONT charge you again,it'll just re-download.No worries,it's not gonna cost.Then once it's downloaded,go on it,create a test Family,then go off of it onto the Main Menu on the iPod/iPhone,then back onto the Game.It should've saved.
Let me Know if it worked for you,because it worked for me.
How to Delete An APP:
On the iPod/iPhone Main Menu,press your finger on the app lightly,and hold it.Then all your App's will have an,'X' on them,click X on the One You'd like to Delete.
IF I LEFT OUT ANYTHING,LET ME KNOW!
