Email has Changed..Need help logging in

Hello,
I have purchased MCEBuddy in the past but it was with a different email address that I no longer have. I need to somehow login using this old email address, or change it. How can I contact the admins to resolve this. I looked for Contact info but I could only find how to change or retrieve your password using your email address (which I don’t have anymore)

Any help would be appreciated!
Thanks
Flan
