I've tried for more than 4 hours to complete this registration.
First, it put me on the eu site. I changed it over to na but then it wouldn't take the confirmation code
I downloaded FFXIV but it won't take the username and password
This site doesn't recognize my purchase
The registration code for the game doesn't work on this site to update to my account

In short, this stupid system is broken. I am about to ask for my money back.
