Ok, heres the the thing, i was had to go, but im back.
I was in tamatown, and i went into the music store, i looked at the inventory, but i couldn't afford anything, then i tried to log out, but then the logout button got stuck, then i saw this text in the room, i copied it, then i posted it here. I really , seriously saw this, im sorry i didnt screenshot.
It's probably coded by a Japanese person, and the message is probably just a status / error message which would help him (or her) troubleshoot problems.
