So once you pre-order the game from digital river, the copy from the Sqaure-Enix store. You will get a receipt (Confirmation Email). In this email you are going to look for a specific line of information. It will be under Pre-Order Bonus Package. This is your registration code to register and -then- get your early access code. The code is in the format of XXXXXX-XXX-XXXXXX-XXX.

Proceed to http://preorder.na.finalfantasyxiv.com

The first thing you will need to do is login. Then your page refreshes. Select your country and put the code in explained above.

If you are successful, you will get a new page that says Congratulations and gives you your "Early Access Code"

You will then need to load your launcher and attempt to login. You should then get a page that tells you, you haven't registered. There is a link that you need to click on that will take you to a web page and allow you to put in the "early access code"

Once you do this, restart the launcher and you are good to go. Hope this is helpful for some people.
