Can't get Pixel Streaming Demo to show HTML5 Overlay

I’ve followed the Pixel Streaming documentation and have it running perfectly. However, when I use the Pixel Streaming Demo project, I can’t get the HTML5 overlay/interface to show up. I’ve copied all the correct files to the proper places. I’ve methodically repeated the Pixel Streaming Demo and Getting Started with Pixel Streaming documentation 4 times now. I’ve tried Chrome, Firefox and Explorer. All I get is the game. I’m not a coder so I don’t know how to manually connect the game and the overlay.

Anyone else had this problem? Any ideas?
