There appeared to be some issues loading up the Tracking202 Tutorial Videos on most browsers. We have since fixed this issue, and now all the videos should load correctly if the DivX player is installed. We are going to be moving away from DivX player in the future, and we are going to put together a written documentation guide for using Tracking202 as well. If the DivX videos still do not work for you, you can find all of our tutorial videos on google in the mean time.
