I can't use it, the "Toggle dog tag frame" doesn't appear anymore. Usually if I log out and log in again it works but this time it doesn't :/

Oh, and for the information, I've used it before in the past, I activated my limited edition code successfully on the day I installed the game (pretty much the day it was released)

It's back now, never mind
But still... wtf?

There were authentication server issues... yet again.
