I received my copy of FFXIV ARR OST today from fedex. Opened up the jewel case and noticed the code was on the inside of the spine insert this time. Proceeded to the mogstation to apply the code and got an error that the code was not valid.

Is it because of the release date?

Is it because of it being a cdjapan import?

I'm banking it's because of the release date but want to be absolutely sure as it does have an expiration date on it as well.
