I have noticed that this subject was been mentioned in many forums. I have had the usual problems getting the disk version to install etc but, after getting some assistance from Aerosoft, I have successfully got it running. So much so I have not had any hickups as yet, even down to running the sim WITHOUT Disk 1 in the drive! I have the Premium Deluxe version and my hangar is full of the correct aircraft, all available for use. My logbook is being updated as I go through the training. I don't know why I can run it without the disk in, (the only thing that Aerosoft told me to do which I have not seen anywhere is to ensure all Xbox services are selected to Automatic in Task Manager. Perhaps that has made the difference?
