I donated some time ago 10 to skip queue on Icecrown, since then I've come back to Lordaeron. 3 days ago I put my lvl 80 lock on the market and it got sold immediatly-lucky me- and I purchased the Celestial Steed.
Now I can't enter the game, I have a new window "Authenticator" under the password one and I have no clue what that is. Before that window appeared every time i tried to log in-today- i was requested a code...i received like 3 mails with codes, none worked.
