Restoring purchases :(

[Juslas]

Many Outwitters fanatics have multiple GC ID's
some of us have multiple devices, making easier to handle multiple Outwitters identities ;-)
I have restored my purchases several times on multiple devices, since I sell old iOS devices and tend to buy new ones on yearly basis ...
It is vital to log in to App Store with the iCloud or App Store ID that you initially used to purchase IAPs.
You can run separate Game Center identity and have a different Store identity on single device.
I understood that you have entered your STORE identity and not by mistake your GC id, maybe it is because you do not have credit card tied in to your account. Therefore because of App Store handshake you have to had credit to validate your restore purchase request...
like I said, since I have credit cards unlimited credit, I can only guess, what could resolve your problem.
