AVG Protection

Hello Andre,
I see that your sales number already registered with your AVG MyAccount and your AVG Antivirus will expires on 8/27/2018. I have sent you an email with the AVG Antivirus full license number, please check with your mailbox and reply to that email if you need any further assistance.
Best regards,
Alok.

I bought a avg antivirus protection and when I try to put in the sales number and register it says that the number has already been registered in the database. Not sure what I should do here to make the code go through.
