I am getting two errors when trying to purchase a sound bank:
Order not completed, data is not valid
Error processing transaction: Message Gateway Rejected application_incomplete Code: Text:Unknown()
All the information is correct for my card, but I noticed I wasn't asked for name and address.
It would also be nice to have some animation showing that our request is being processed when we press "buy", I can foresee many people will be unsure if they clicked properly...possibly resulting in many repeated clicks. A down-state button color would help a lot.
