[BUG] Avast free antivirus lose license

[REDACTED]

Click activate and choose Free license again but nothing change.



Seen still working, explorer scan working too.



Only can update virus definitions, the update button for program can't click.



Same, clicked  "buy now" and choose free license again and nothing change.

Using Windows 10 Home ver.1709 x64 Chinese language, few days ago have same issue when Avast itself program update reboot.
Reboot system also nothing change.

Please help me get rid of this annoying issue.

[REDACTED]

So no any reply in one month and a version update?
It came back to normal several times BUT most of time in this month it work without license.
