Spent $20 on it and I cant use anything!

When I start the game I can just about anything except restoring my old purchases (because I moved to an iPod 5) and when I hit the restore purchases button, It would freeze and then crash. Please fix this, Ive spent some good money and I dont want it all going to waste. Thanks!
