Error message on the unilearn theme

Hi, i’m trying to import demo contents with “Cws demo importer” “theme: unilearn”, but I get this Error message “ Most likely the purchase code you’ve entered is incorrect, make sure there’re no typos.

Your code should look like this - abcd1234-ab12-cd34-ef56-abcdef123456."
Contact us if you thinks it’s a mistake.

Is someone can help me.
