Default flight is set to "The Airport I'm Working On/ultralight". I close the error and FSX loads OK. The selected aircraft window is black because there is no ultrlight. Go to select aricraft and just the few planes I wanted are there. If I put the ultralight in the new folder, there is no error. I'm sure there is a way around that, but it was just a quick experiment. I don't have a lot of addon planes, but I know many do. If I just wanted FSX to load so I could check on an airport I am working on, I wouldn't want to wait five minutes to do so.Bob

Hey Scott,No, the SWREND switch doesn't do anything anymore (I believe the software renderer we were using was only DX7 or DX8 compatible).
