Hi

Ultimate FAQ Guide

Why can I not reactivate my FFXI Account?

Final Fantasy XI has two different versions of PlayOnline. Version 1 is based in the North America, and Version 2 is based in Europe. If you try to access an account based on a different Version of FFXI, you will not be able to access the membership area.

You may have a problem trying to login to change information in your membership section in PlayOnline. This is because you purchased a FFXI account with a different FFXI version (example you purchased an Europe version when you are currently accessing an USA version). In order to fix this, you will need to download a different version which can be run as a second application on your desktop (it will not overwrite your US version).
