License: problem is available – Kaspersky

Hi experts,
I want to update anti-virus but in a number of cases, I get this message: "License: problem is available" may appear.
Moreover I find the error message "Black list of licenses is corrupted" is showed in the Security troubles window.
Nut you can run the Security Problems window by selecting on the display sign in the central application window.
I need to solve this.
Please help.

Black list of licenses is corrupted
One of the possible reasons is incorrect update. Protection is disabled.
Protection components
Kaspersky Anti-Virus Self-Defense is disabled
In case of a virus attack the application may be rendered inoperable.
We recommend you enable Self-Defense.
Thanks a lot.
