I find that Creative Grids do not write the best instructions on how to use their products. What might help you is viewing their instruction video in slow motion and in full screen. Sometimes the demonstrator goes too quickly.
To slow down a YouTube click on the Settings icon (which looks like a gear/cog) and select which speed. Then select full screen and when viewing hit the space bar to pause and space bar again to start. I find this helps me when I want to follow along.
