Every time I launch the installer on DVD #1, the installer jumps up and down in my dock, then crashes and disappears. Only the Installer Log appears on my desktop, and nothing else happens.
I have the web demo version installed, which works fine, and it recognises the DVD and allows me to use the Demo version as normal. But I can't seem to install additional planes or locations, which is why I was trying to do the normal install.
