Ive decided to give ff14 another shot. Im trying to reactivate my account,but my old login and pw seem to not be working..so i registered a new se account. When i go to add a service account to my log in page,it says that my code is already in use (from my first account.) i cant seem to get my old log in (syas that email has no account?)
You can't just register a new SE account and slap your old XIV account onto that; that's not how it works.
You need to contact SE and have them provide you with your old SE account login information. I'm not sure if you can get the login name via web-help, or just the password, but their customer service phone number is in the Info/Links sticky on this forum.
