I'm having issues with the PS4 version as well. Around 8 am, It glitched and kicked me out of FFXIV. But after RE-installing 2.0 (twice), I was able to log back on. Played for a few hours and logged off.

Now i'm unable to log in again. I'm getting the message: "An error has occurred. (NP-36147-1). No word from Sony. This is just great. And to think, I just payed for another 3 months of ps+.. This is getting ridiculous.
