Account no longer has Stormblood access

I preordered Stormblood and played for a couple of the early access days but had to take a week long break due to work. I come back from my work week to find that my account no longer has access to Stormblood for some odd reason. I tried putting in my Registration Key again but it states that it has been already used. And I can't login to my character because it's lv 61 and in a SB area. Has this happened to anyone else? I'm not willing to purchase the expansion again.

I'm having this same issue ><

The key you registered was your early access key. Not stormblood.

Early access has ended and you now require a full key to continue. Check your emails from where you bought it or your physical box if you bought it for the key.
