Early Access codes invalid.

[Pnzar]

Hello, i currently have preordered FINAL FANTASY XIV: Heavensward Collector´s Edition box for PC from the EU store.
Now i`m reading that the early access codes is redeemable on mogstation.

However, when i try entering the code it keeps giving me that the code is invalid.
My account is under "Region: Europe & Other Regions"

I`ve tried the code you find on http://eu.square-enix.com/en/heavensward-preorder
Aswell as every code i`ve gotten on e-mail, none are working.
Is there a way to fix this issue?

I bought the base game on steam, and the Heavensward CE box(physical) on the online EU store.
Help would be appreciated.
