I downloaded and installed it. So far so good - I didn't explore all of the program - except for choosing the external editor. The program quite rightly chooses Photoshop CS5 as the editor but refuses to open in CS5 stating that an external editor isn't selected. I checked preferences and it is set as default. When I choose the second option in preferences I can "force" it to open in CS5. This however means that the second option can't open an other program.
