@centrescene: I have sent you an email and have attached the files.
To import demo content file
Go to => Dashboard => Tools => Import => WordPress (Run Importer) => Browse and select the file audiomanpro.wordpress.2018-09-07 and click on update file and import. Then assign authors for the imported posts Check Download and import file attachments option then click the Submit button.
To have the customizer settings same as that of the demo. You will need to use Catch Import Export Plugin. Install and activate the plugin.
Then Go to => Dashboard => Catch Import Export => Browse and Select the file audioman-pro-export .dat for import and Check the Download and import image files? option and click on Import.
Let me know if this helps you out!
Kind Regards,
Skandha
