  • I am having trouble viewing the video lesson. What can I do?

    The large majority of time video issues are browser-specific. For example, it may be that you have a plugin installed that is blocking the videos or your browser may not support the file type you are using. Try using a different browser or an Incognito/Private window instead. If this does not correct the problem, please contact us at
