They would probably sell more if people could test it first. It's a graphic app, so will it work on my system, with my OS, my graphics cards, any glitches I should know about etc, etc....how easy is it to use compared to 4 etc, etc... Don't answer these questions, these are the things I would want to see for myself, but, as I already said, since I can't evaluate the program, I won't buy it.
