I just got FS one and installed and it sometimes it opens with no runway or landscape detail, just bare ground with the plane in the middle of nothing. I can exit and hit "fly" again and it will usually load correctly. It also sometimes closes on its own with no warning or error messages. I have to click on the shortcut and re-start it and it will do fine until I change something then it will close again without warning, the changes I made are usually saved but its very annoying, is this normal?. Do I need to un-install and re-install it? I have a 2 yr old HP media center Pc with Xp. Any help would be appreciated!!!!!!
