New install does not show demo homepage with a menu

I have had to completely uninstall my first attempt with this theme due to many issues. After brand new install, I do not get the demo homepage with a menu like it was on the first install. I have tried to make a menu, but it does not take me to anything. Do I have to make pages with this theme? How does the menu correlate with the scrolled sections like “about me”, “services”, etc. I am finding this theme extremely difficult to customize. If I have continued trouble with this theme, I am going to abandon it, waste of money, and go to another vendor with an easier configurable theme. I have installed and customized other themes with no problems. Www.rjgraphicsunlimited.com
