I am presently using Vista Ultimate as the operating system, but when I have download the new FSX PDMG 747 programme, this is fine, but after loading it up and getting ready to fly, when I start FSX up and select any of the PDMG 747 aircraft, the programme sits or hang for a while and then restarts continually.Suggestions please to this problem.
