Hi Carl. It runs fine for me on two PCs, my phone, and my tablet. No complaints from other users. Sounds like it's something on your system. Are you watching online in the Theater or did you download the ZIP file?
I'm out of ideas, Carl. I just tried again. Let it play from the beginning right thru that time index. I'm at 3:30 now. Playing fine. Has to be something on your system. About 500 people have watched this course so far with no other complaints. Try downloading the MP4 file. Click on "Download Mode" in the settings frame (bottom left of the Theater) and then that should let you download the video file to your PC. Maybe there's something going on with your browser and my video player.
