The instructions on your install page say...
"Log in to your backend of your Magento Administration and go to "System" →"Design". Click "Add Design Change". In "Custom Design" select your theme from the drop down and click "Save"."
In System>Config>Design I don't see an option to add a design change.
I'm running 184.108.40.206
I tried to installing the theme on 1.4.2 and was getting an error every time so I assumed the template was not supported in this version.
