Despite purchasing a lifetime bundle, it warns "Your license key is invalid"

There are two plugins I installed: meta-boxmb-settings-page and meta-box.

Is there anything related to this problem that nothing is displayed in "Download" at https://metabox.io/my-account/ ?

Have you purchased any premium plugin?

I purchased a lifetime bundle to use meta-boxmb-settings-page.
I can download it from the link in e-mail sent after purchasing, but not from my-account.

What was your email when you bought it?

It is the following.↓

The email address I registered when purchasing the Lifetime Bundle is "[email protected]".
However, this email address is incorrect and does not exist.

I confirmed it. Thank you very much.

I have a question.
If I change my email address again, will the same problems occur?

Thank you for your answer.
