If you have done a sync to iTunes on your computer you may be able to retrieve the game it depends if she deleted the backup info from your iPad and if the backup info is saved to iTunes. If not then sorry to say you will have to start from the beginning.
Thanks guys,
I downloaded the game from apple store to my iPad and seems that the only way to restart everything from the beginning .... Which is tooooooo boring for me , I like the game but It is time and money consuming.
Thanks again, hard luck for me ...... Damn!!!! I don't know why I allowed my kids to play with the iPad, big mistake
