Apps not downloading from AppStore?

Question

macOS

MacOs 10.8.4
Please tell me, I don’t remember exactly what happened, or it happened by itself, but when I download a paid or free application, it asks me to enter a password, I enter the email in the window (the field is automatically filled in) and the password window. The verification slider is spinning, and nothing else happens. Already restarted, and demolished the cloud, and changed the password and did a new user, nothing helped. It loads from an iPhone, but not from a poppy ((
