just to be clear we're talking about the Serial Number/Product Code in the order confirmation email I got when I ordered right? Cause after that email I have received no other, but it does say that the game is registered on my SE account does that count, even though I got "There was a problem, Please try again".
Now that's curious. I just noticed that I have XIV registered on my account as well. Does that mean...success?
Maybe that's why I was getting the "There was a problem with your code. Please make sure you have entered it correctly." message.
