If you are receiving this error, it is likely due to a connection issue with the iTunes store. In most cases, you will be able to tap the "OK" button and receive your purchase. We also advise rebooting your device, and force refreshing the application. Do not attempt to reinstall the application as this may download the purchase to your New User account. Occasionally iTunes may experience payment delays, so please allow at least 1-3 hours for the purchase to clear their system.

If you have tried all of the above, and are not able to access your purchase, please contact iTunes support so they can clear the purchase and allow you to re-purchase.
