The course will actually lose your place (like a book closing without putting a bookmark for you) if you:

• Are gone from the course more than 45 minutes
• Lose your broadband connection, even for a few seconds, as the course needs a consistent connection to save the data

Be sure you passed the QuickCheck test. If you did, and the videos will not launch, be sure your security or firewall settings are allowing you to reach these two sites: "app.ninthhouse.net" and "media.ninthhouse.net."
