I purchased episodes 2-5 on my Iphone 4 earlier today using credit from an iTunes voucher. (I have played episode 1 and really enjoyed it.) However, I didn't have enough signal to download them so I waited until I got home, but although the credit has been deducted from my iTunes account, the game insists that I gave to purchase a new episode if I want to play it.
Do you know why it won't let me play the content I have paid for, or how to update it so that it will register? It did at the time of purchase, I just couldn't download it at the time.
