Just got off the phone with SE NA support. Called right at 9:00am (PDT) and was on hold for 25 min (not a complaint, just a forewarning). They were able to confirm that my account had been registered and I was going to be able to play EA. The method I used to get my 18 digit code to work was to go to http://preorder.na.finalfantasyxiv.com/ and hit F5 and log in before clicking the flag for my region. After I entered the 18 digit code I was redirected to a page with my 20 digit code which I entered here: secure.square-enix.com/account/app/svc/ffxivearlytop?rgn=na&lng=en I had previously received an email with a EU code (which obviously did not work). This process was a second attempt at registration. I did not receive a confirmation email but after speaking with phone support it was confirmed that my account had been registered.
