ID has already logged in, do you want to log in again?

Hi desertfox. This is the error message you receive when another person has logged into your account whilst you're logged in yourself. This being said - I have also received this error message many times and I would say ninety nine percent of the time it is simply a bug and nothing to worry about. I would recommend changing your password to be double safe though - Just to cancel out that one percent possibility that somebody has your password.
