We see that you also have AVG Password protection and AVG Secure VPN which can be activated using email address but Antivirus will get activated using license number. It's not possible to activate both license and email on same device, it might work for sometime but will get conflict with each other.
To fix it, we request you to migrate your AVG Antivirus (2 computer) into AVG Internet Security Unlimited which is free of costs. I request you to contact our technical support team https://support.avg.com/support_contact_form?l=en via online chat to perform this free migration and assist you further.
