I R a computer dumbtard and have 3D. I read the directions of how to set it up many times over. Cooked my brain for many hours and could not figure it out. My son who is hot on the computer had some problems helping me out, but eventually got it. They offer classes that you have to pay for on teaching you how to use it. Does that tell you something? It works well, but at any moment I'm waiting for it to screw up and I no longer pay the yearly thing. I'm going to get a newer computer soon too and 3D tells me that my system won't work on a newer one, but they be happy to sell me a newer version, bless their hearts. I'm glad Philip asked this question because I'll be looking for another system too.
