Login problem with BlueStack

#1

I started to play second account with PC and BlueStack, but I don’t know what “my problem is” with google account or is it game related. I want to play this awesome game outside my home with another PC, but I can’t login.

Free translation:
Account not supported

nonnonoo@gmail.com (example)

Unable to log in with this account.

I made family account from my main account and I have allowed every game (no age restrictions) ect. But Can’t login. From time to time I get notice that: My heroes are not safe. But how I can login to that account?

Bluestack is logged in to that account and I can see from google account, that I have played Empires, but login just wont work.
