Problems with installing all of Highend

I was on my hosting site and purchased a premium theme, Highend. I like the corporate one page. I had to make the purchase in Mojo Marketplace. There are multiple download files. From what I’ve read, I should down the “main theme” file, which is 5+MB and the Highend WP folder goes into my themes. All good so far and I can see it and activate it.. but all of the image for the demo imports are missing and the links do not work neither does the plugin button links. I see in the full multi download files from Mojo there’s a 19MB file consisting of 4 more zips and one of those folders has a demo data folder that shows 12 options. Now what do I do? Please help.. frustrated.
