Heya, I decided to buy the game with two days left on my trial, so I went and purchased it from the NA Squeenix store (Since it's only $10 there and it seemed like the best deal), but they haven't given me a code or anything to upgrade with. I've gone into MogStation and it just asks me for a code and when I look at the order I've placed it says this:

When requested, please enter the product registration code to complete the initial registration process.

But I can't see this product registration code anywhere.

Mildly concerned, since it's already taken my money and I have no code

And the game hasn't upgraded itself or anything, I checked that and it's still a trial
