I have installed X-Plane 9 on my Windows 10 PC. However, when I try to add more scenery and when it asks for disk 2, I insert disk 2 into the computer and click continue while nothing happens. I have tried downloading the X-Plane 9 DVD installer from the X-Plane website, and it still didn't work. I can access the second disk in Windows Explorer. I have tried installing the program on my external hard drive, and it still refuses to accept disk 2. I tried using a different DVD drive, still nothing.
