Impossible activate licence

I renewed my subscription to AVAST CLEAN UP. But impossible to activate the license(Bachelor’s degree) from the tab subscription. Message error = An unexpected error occurred on the waiter(server), we work to solve her(it). Administrator or not administrator. But it has been already 48 hours since I try. Not sure message is true.

Contact avast and ask them to have a look. > https://support.avast.com (create a ticket there)
