Cannot play on PS4 - logs me out of PSN?

*UPDATE - Well if you come into this problem, just turn off the PS4 completely, turn it back on and try again. :P That fixed this issue for me.

I'm having an issue playing the game on the PS4. I hadn't played in weeks, started it up today and it updated the updater. It then asked me to close the app and start it again. Did just that - it starts checking my version of the updater, then gives me a screen saying "You have been logged out of the PSN. Please log in to play Final Fantasy XIV.".....but I'm currently logged in to the PSN, so I have no idea why it'd say this. I back out, log out, log in, restart the game, and get the same message. This never ends. Anyone know what's going on with this? Do I have to delete everything and redownload the entire game?.....Because that's not cool if it's the case...
