Will my profile save after this, and what happened to the game?

Dragon city for my iPhone stopped working, when I would sign in it would exit me out. So I decided to delete it and download it again, and I signed in with Facebook. Than it just kicks me out again. Will it sign me in, and what happened to the game how can I get it to work again

Is that a original copy of the game?
However I think you Id is blocked, email the game makers or insert a new fb account:/
Or maybe there's a problem or bug with the game, make sure you're using latest version
