"Your Code Has Already Been Used"

[Tyrial]

Right next to the "instructions" button there should be another button, I think it says "Download" or "Activate". Pressing that button will give you the code that you need to use at https://preorder.na.finalfantasyxiv.com to select which platform you want early access on and then it will generate your early access code.

Yep, I don't have the "Download" button. It just shows "Instructions".
