Hello! Good night everybody.

I in the year 2016 bought the Purple Dino theme from the arcademug.

I would like to use this theme again.

I try to install the theme and it gives error in the license key, it says that the license key is not valid.

See the image of the email that I received from the arcademug when I bought the theme: https://ibb.co/ePc6V8

You can see that I bought the theme and this license key is the one that came when I bought the theme.

This license key is no longer working.

Could someone tell me how to cancel this license key so I can actually install the theme?

I await your feedback.

Thank you.
