Can not access my account due to old Email address

My old Email address no longer exists and I would like to log in to Parallels.
I do remember my credentials, but unfortunately it is required that I access my old Email to confirm log in, which I no longer have access to.
So it is not possible for me to log in to my account to manage my subscriptions and license.
Is it possible to transfer my licence to the new email address?

Thanks in Advance!
