Lately, FSX has had trouble loading flights. About half the time when I either try to load a saved flight or just create a flight FSX tells me that loading is complete, and then nothing will happen (sometimes when the loading box disappears, the screen just stays black, too). I was lucky enough to actually have a flight load today, but I didn't have it going for long until I decided to change the settings. After the flight "loaded," I was met with a blank screen? Does anybody know what might be causing this, and if there's a fix?
