Im fed up with this!

I have a subscription to your magazine and this time, I cant read any of my magazines. This months issue says its corrupted. I checked random issues and they all say that and I cant open them.

I restored my purchases and I get the same message. The all sitting there saying "read", but I just get the error message.

Can you please fix this?
