I went back and clicked on one of the sliders and was presented with a button and a new tab. That at least gives me some indication of something to do. But it wasn't until I actually clicked the button that I got anything that might resemble content. That's also when the walk-thru pop up appeared. Don't make the user have guess. Also, very unexpectedly I actually felt intimidated by such a blank screen being presented to me. It felt like being dropped into MS Word or an IDE for the first time. It wasn't until I had stuff on the screen I could interact with that the (slight) anxiety went way.
