This is the third time that this type of problem occurs with me: when the game requests the code of attention and I put the code that I receive by email, this code is refused and I receive another, which is also rejected and I am in this looping almost infinite. Today it took more than half an hour of game trying to log with a code that the game accepted my access. Honestly, I think this is an improvement in game security, seeing what happened to Molten, but this kind of error can not prevent the user from accessing the game.
