Hi, is the free trial only for steam? I tried to register for a free trial account through the website and i had gotten my square enix account and also mog station acc

yes i did, i tried creating my game account from the launcher but when i try to login it gives me this error "You could not log in because the service account in question is not registered. If you would like to log in to the service, please log in to the Square Enix Account Management System and register the service acccount."

I did log in to the Square Enix Account Management system but it only asked me to add the services of the "A Realm Reborn" product key if i did purchase the game
