Trial version key

Hi all,
I have just downloaded a trial for Rhino 7, and received an email to complete the login process. When I clicked on that link, I also received the Trial Key, but I didnt copied and saved that key. Rhino asked me to restart, to complete the installation process, and I restarted. When I open Rhino now, it requests the license key, which I don’t have anymore.
Can you please assist?

Enter your email into the original download trial page and you will see your key again.
