How do I fix CG Redux Framework error

I bought Rogan WordPress theme via, below is the error I get whenever I install and activate “CG REDUX FRAMEWORK”;

Fatal error: Uncaught Error: Undefined constant “AUTH_KEY” in C:\Users\Organised Noise\Local Sites\lookpro\app\public\wp-content\plugins\cg-redux-framework\ReduxCore\inc\class.redux_instances.php on line 73

I guess it has to do with the license. Please I don’t know what else to do to fix this error.
Anticipating to hear from you soon. Thank you.
