Have you upgraded to the last version of Plarium Play Commander?

yes

I was playing normally but there was a red dot on the top of the game loading screen, when I want to open it again after pressing it, it fills up one hundred percent but a black screen occurs and the game does not open. 

Can you check if I give my password and account? 

Yes I can but I dont want you to put that information here on the forum.
