Dear Customer,
Regarding your request for account support. Please find your answer below.
If you played FFXIV version 1.0, you cannot use a registration code attached to a Windows version FINAL FANTASY XIV: A Realm Reborn Collector's Edition package. Instead, you simply need to purchase the Collector's Edition digital upgrade.
More details can be found in the following URL:

For more on the digital upgrade, click the following URL:

If you have already purchased a Collector's Edition package, please note that we do not accept any returns. If this is the case, we advise you to create a new service account.
Thank you for contacting the SQUARE ENIX Support Center.
