Not resolved just got the error 304 (6:3:1470:266) this account it already logged in.
I was looked in a 3 min load screen and shut application and tried to restart - this is what I got.
I can see some people have been upset by this on a guild (psn chat) so I'm going to imply that there may be more without access to this forum, who can't tell you.
As the standard submit a ticket for this not on forum is done through game... I think there may be a few you are unaware of who can't report it too.
