Same thing happened to me. I cannot log in to the website but I can log in to the game. Everytime I try to log in to the website I get redirected to the "Admin Account Support" which you need to fill out.
It told me I had the error 7767 because of account sharing and to be honest the day before this error I just simply log in using the PC (I normally use the laptop).
It took a few days before it was fixed. Just send an E-mail and it should be fixed in a few days
