Failure to install

I purchased AVG Secure VPN 2020 - 5 Device 2 Year from Amazon UK. I tried to install it on a laptop operating Windows 10. After I had Entered a activation code, a message came up telling me to try later. When I tried later, a message came up telling the activation code has already been used. Please advise
