PS4 Cannot Verify the license, booted from game

[Cakekizy]

I was just playing the game and got a message saying "In 15 minutes FFXIV application will be closed because it cannot verify the license" and 15 minutes later it booted me from the game, and now I cannot log back in. All it says is "Cannot use the content. Cannot connect to the server to verify the license."

I was under the understanding that since i bought the game from the playstation store that I didn't need to enter any codes, or whatever everyone else had to do. So i'm very confused, please help. D:
