I received my copy of Realm Reborn today and every time I try to access the game, I get the message 'No Valid Service Account'. I didn't receive an early access code, so I thought perhaps its because the games official release is Monday on PS4. I figured the servers are already in place though. Has anyone else had this issue?

I've played both Beta phase 1, and Phase 2 and used the registration code in the box for the PS Store and the Square Enix EU website.

Any idea what the problem could be, or a potential work around? I'm stumped.
