I’ve uploaded the demo content at your wordpress installation and updated the home page. I guess you’ve checked the download attachments check box, which would not load as Images are not included.
You could find all the pages and post on the preview ( no Images included due to copy rights ) and if you wish to use any page just go to that page and Edit Page -> Update.
Another way to get demo pages, particularly great if you want just a few pages and not the whole content is Loading templates as in the attached image, Just add a new page and Click Load template, and find the name of the page you want.
