Cant use my AVG TuneUp key

I tried using my key that I just purchased but I keep getting a "Sorry, something went wrong…"

Hi Lucas,

We'll certainly help in activating the progam.

On checking, you have purchased AVG TuneUp subscription valid till Nov 13, 2020.

I have sent an email requesting more information, as it is not advisable to provide account information in public post.

Please check the email and revert back with the details to assist further.
