Having used avg for many years, it was renewed/upgraded the other day and the new version installed. All was ok for a few days but then it came up with error message asking for licence number to be reactivated. Did this, but it always fails. Tried reinstalling avg, that failed toio - error code 0xC0070643

Tried to get through to support but the phone number doesn't answer. Any ideas?
