Okay. Thanks for the info! I was told by another person on here and opaque as well that it works on Windows 8 and up, which is why I went ahead and updated my PC laptop to Windows 10. I’m also going through the other information you previously sent me that has a plethora of helpful information. So basically, I believe I’m going to go ahead and purchase the K4U Example Levels so I can get started with that and I have the K4U Intro already, which I’m guessing is just a guide, so to speak.
