Hi Miggy! I'm going to refer you to this web page,
https://na.nasomi.com/start.php
Often players don't realize you have to create an account on Nasomi and second create a game account from winthin your Nasomi account. After that you launch Ashita and the game account is the name and password you use to open up the FFXI create your character page,
Hope this helps.
