Hi,
Are you using any of the Front Page widgets? If so, take a look at this link – https://appfinite.com/tutorials/how-to-setup-the-home-and-blog-page/ They should automatically show up on the homepage once you activate them.
You can set the “Front page displays” to “Your latest posts“ on the Reading > Settings page in your admin. Then whenever you add content inside a Front Page widget they will show up on the Homepage automatically. This means you won’t need to create a “Page” for your Homepage as the Front Page template will display as your homepage.
If you would like for me to login for you and activate this just let me know. All I would need is a temporary login.

I tested the demo content download link and it seems to be working. Are you referring to the Dropbox link from here? – https://appfinite.com/theme-setup/aspire-theme-setup/#ihp
