Yes Sara, Vue 4 will read all scenes from Vue 2 and 3 and you also can use all your plants. To be sure to keep always a saving of your plants, so that you have not to re-install if there is a computer problem, save your plants folder to a CD or some other support. When you need to re-install Vue, you just have to copy back your plants in the new folder. Sorry not to have time right now to see your pictures, but I will go there soon. :-)Guitta
