Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
It seems like you purchased the plugin with some other email address.
Can you please search and forward a receipt from FastSpring.com so we can locate your account? You can add them in the designated sensitive data section

It is completely secure, and only our support staff has access to that section.
Thank you, and looking forward to your update.
Hi:
I had an account with RankMath already but when paying, I used PayPal and that’s when another account was created somehow. But I already downloaded the file and installed into my backend. It’s working so far.
Thanks,
BRYAN LUNA
