Hi BeatSheep,
You probably switched Apple IDs since 2011, meaning that you logged into the App Store with a different email address back in 2011.
If that’s the case, here’s how to login with your old account in order to download Music Studio (or any other app that you purchased back then):
- Open the Settings app from the Home screen
- Go to “iTunes & App Store”
- Tap the Apple ID, then tap Sign Out
- Sign in with your old Apple ID and password
- Open the App Store from the Home screen
- Music Studio should now have a cloud download icon, meaning that the App Store remembers that you already purchased it.
It this doesn’t help, or if you only ever had one Apple ID, please drop us an email at support@xewton.com and we’ll look into it further.
