I have photoshop CS6 extended version. I want to play around with the 3D I even found some beginner tutorials on youtube. However, all of the 3D menu is grayed out. When I googled it the only answer seemed to be uninstall it and reinstall it. There was something else but I don't remember off the top of my head. I think it was something about the activation code. I wanted to check here to see what anyone might have to offer.
