Every time I open the game , it says that there was error with sign in . I have played game before and uninstalled it , after a few months I downloaded and installed it again, but game always gives me one of two types of error !!!
First :
Sign in could not be completed.
Second:
Unable to connect. This may be because you are not connected to the internet or your network connection is not configured correctly.
I also tried to turn of antivirus (Smart Security 8) but it didn’t work .Please help 
!!!
