Cannot contact theme creator

Envato Authors Theme Authors

Hello, I am trying to contact the author of a theme that I have recently bought, through his website, where he offers support for the theme, but when I try to register, I am getting an error saying that you don’t have made any purchases.
Any help?
Thank you

P.S.“the author of the theme is pixel grapes.”
