i followed the prompts to log in and it said " i currently possess a square account" which i do. So when i go to log in it gives me the red text

*Pleae quit the game, sign in with the Sony Entertainment Network account that you used to download the client. Then re-launch Final Fantasy XIV*

I use the same PSN account for ps3 and ps4 yet it won't let me in. Is this because i have a disc version of FF14?
