Avast add-on with problem.

Guys, as soon as I open my email manager, the Avast add-in has a problem. How do I solve this problem?
The email manager I use is Outlook
Attached is the image of the problem.

Google translate gives me: “NO monitor this supplement for the next 30 days.” 3rd bullet down. Explain please.
