Teach Yourself VISUALLY Power BI 1st Edition

The sample files rely on a seperate download from Microsoft. Have the download and the sample files but I'm getting an error. I was on the tech chat for an hour when I got disconnected. I'm not sure why the author wouldn't include ALL the files like other authors of tech books have included. Don't get me wrong, it's a great reference but as a learning tool it's problematic to see examples that you can't work.
