FAO Mods : I have recieved 2 early access codes

[Ecks007]

I have an activation code, but it doesn't fit the format to be entered into the Mog Station, it's basically formated as 6 letters-3 numbers-6 letters-3 numbers. Is that the early access code? And if so.. I'm not sure.. oh wait, do I enter that on the Heavensward site?

Edit: It says activation key.

Though I swore I did all this already I can't seem to find the emails, in fact I'm sure I never received any. I just checked everything on the SE store.
