In app purchases and account don't carry over – F.A.S.T. -- Fleet Air Superiority Tactics! Review

I loved to play this game on my iPhone 4. Had it on my iPod touch before that. However, when I got my iPhone 5s, I went back to play again and none of my in app purchases, my user name, or any of the planes I had unlocked were saved in there! When I went to put in my account name, it told me that the name was taken already, with no clear option to sign in. Disappointed because otherwise a good game
