Every lesson starting with the "Slow Jam: Up One, Down Another" lesson until the last lesson in Ben Lindholm's 10 Ways To Play Arpeggios course is missing the video.

I tried in both Internet Explorer 8
and Firefox 10.0.2.

I am also having the same issue with Hanspeter Kruesi's Basic Rock course
All Over The Fretboard Megachops Fm lesson
