Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
Sure, please share the email address you used to purchase the PRO version and forward a receipt from FastSpring.com in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Looking forward to helping you.
Thank you.
