Hey Paul,
The Themer for Hueman has created a style.css for the child theme that will work. You can find it from inside your admin.
Go to your Theme Options page from the left hand navigation of admin panel. In the upper right you’ll see a little drop down Help menu.
When you click on this you’ll see some links to the left. You’ll see ‘Download the sample child theme’. This should help you on your way.
Hope this helps!
