We also require proof that this is your domain. Can you create an account using that domain as your email? Otherwise, we would need some other proof to verify that is your account.
Best Regards,

Darian. Thanks, I found my email after sifting through my password manager.
Twas an all-nighter, but I found it. I even remembered the correct password, but the email ID was the issue. Guess I have to clean up my password manager and have strong backup strategies.
I am now able to access the account and the license. Thanks again for your quick response, thanks a lot once again.
