Hi,
When you install the package with sample content the demo site pages automatically will create on your site.

The site is already installed and contains my own content. I want to see how you created the new blocks with the updated version. Re-installing the theme is not an option for me.

Hope you have a demo
Luca

Can't you install a new version on your localhost as a reference? unfortunately we already do not have a demo site which allow other users to login.
