Today I am attempting to redeem my pre-order code at preorder.na.finalfantasyxiv.com, however after logging in and typing my code, the 'redeem my code' button is grayed out and unclickable. I have been trying only for the last hour or so. Issue is the same on all browsers and pcs / laptops. Is anyone else who still needs to redeem their 18-digit code running into this problem? Is this a symptom of congestion?
