Upgrade from Creative Cloud free site to business catalyst paid site

Hi there,

I am trying to upgrade from a free creative cloud site to BC Marketing

How do I "claim the site as a free Creative Cloud site first, before the additional upgrade options will be present."

When I Log into the admin console of my site > Site Settings > Site Management,  the option to upgrade the site to a higher plan doesn't present.

This is all I get http://www.virtualteacher.com.au/images/site%20setting.tiff

Thanks in advance.
