We need to reset the API-KEY…

I deleted Wp Fastest Cache and Premium activator to resolve some issues on my website.
Now, after installing Free version, when I click on “download” link to obtain the premium version I’m redirected to

https://www.wpfastestcache.com/forbidden.php?host=donpi.altervista.org

and the message says:

We need to reset the API-KEY of donpi.altervista.org. Please submit the form.

But, if I insert my email (that I used to buy license) the browser answer:

“Email must be like XXXX@donpi.altervista.org”

Please! Help! It’s urgent
