Ok so I just bought the game, got my confirmation e-mail and code and having errors when trying to register it. Is the game open to download yet or we have to wait?
I purchased the pre-order about two weeks ago, so my experience may be different than yours. If it wasn't for help I received here and reading up on the game over on the reddit subforum, I'd be lost. The information spread and navigation on the main site is horrible - something I hope they fix in the coming days or weeks after launch.
As I recall, I went to the pre-order website from SE and picked up a standard digital PC copy of the game (I'm looking to just try it since I'm ambivalent towards the FF series. If I'd been a fan, I'd have gotten the CE). Although I didn't sign up for an account (Square Enix) at that point, I immediately received a receipt in my email attached to the order and a link to download a PDF.
On that receipt were a number of different numbers, but most importantly, near the bottom was a temporary redemption code eighteen (18) digits in length. After downloading the PDF, I was incredibly confused as to what to do - there wasn't much information in the PDF, except what I think now was the code redemption website.
At this point I remember attempting to try to sign up for an account on the Square Enix site, but encountered a number of problems. After two days of trying to get my request sent, it was finally accepted.
After a few days of not really thinking about it and trying to find information, I found on reddit a post detailing some instructions with the preorder code. At the time, SE's preorder redemption site was having some major problems and I was unable to redeem my code for two or three days. Fortunately, I had success redeeming the temporary code and was given access to the permanent twenty (20) digit pre order, early access code.
After inputting the early access code in my account, I finally received a download link to the release client and I've been happy ever since. I hope this works for you, as I may be missing a step or two. It's a very messy process. Ultimately, I encourage you to read up on the ffxiv subreddit (you may have to scanover fifteen or twenty pages, but you'll find what you need).
TL;DR
- Sign up for a SE account.
- Purchase game. Immediately receive PDF download and receipt in your email inbox.
- The receipt contains a temporary-redemption code which is eighteen (18) digits long.
- Go to http://preorder.na.finalfantasyxiv.com (google to make sure that's it). Redeem eighteen (18) digit code.
- Receive a twenty (20) digit code to register under your account in the SE main site.
- Receive download link to most release client. Install game and patch.
