Did it get to the point where it asked for your iTunes password? Sometimes if in an error occurred in the process shutting down the app completely and opening it again will cause apple data to show up. To shut MixTwo down go to any home screen on your device (a screen where you see all your app icons). Double tap the home button on the front of device. You should see a row of apps at bottom of screen. Assuming MixTwo is one of those...tap and hold MixTwo until the apps wiggle and you see a minus sign. Then tap on the minus sign on MixTwo to shut it down. Now try to open MixTwo again and tap the add coins button and see if the coins show up. If that still doesn't work let us know.
