Only Steam accounts can login through the Steam launcher.
Some time ago they changed how you can login. I've tried booting the game through the boot file, which works until i try to login and it states that 'this service account does not have a valid FFXIV license for this platform or your subscription has expired'. Originally posted by Clammy:So I've just decided to get back into the game, updated my subscription, but when I go to launch the game through steam by hitting play, the ffxiv client will load for a brief moment, and then just quit.
