Hi,when trying to reinstall this arcraft,from the moment I hit "validate" the installer vanish from the screen. Because I could not find the problem,I ordered a new download. With this new download , when I hit "validate" ther's a pop up that says : error code : 0x800C0008,downloading from specified source failed... This is the first time I have this problem since 2005,when I purchased this aircraft. I run Windows XP pro. Someone know how to fix this problem pleas, very frustating. thanks, Philip.
