Deregister my purchase code Accidentally

[esferize]

Hello

I´ve deregistered the purchase code for my site. How can I fixed? I don´t want to purchase the license again.
I copy the text from my dashboard: This installation has been deregistered and can’t be registered again with this purchase code. Please purchase an additional copy of theme in order to get a new valid activation key for this installation.

Thank you
