Hello. Have you changed anything since it last worked properly,  like updating your video card drivers? If so, use System Restore to go back to a point before you updated.

The same thing happened to me several years ago. Two video settings had changed for some reason. Your problem may be different, but check this out.

First, check your video card by right-clicking the desktop and selecting "Properties"; then the "Settings" tab; the "Advanced" button; and the "Performance" tab. Make sure the "Hardware Acceleration" slider is all the way to the right.

Next, run FS2002. When you get the opening screen, select "Settings", then "Display", then "Hardware". At the lower left, make sure there's an "X" to Enable Hardware Acceleration.

Let us know if this was of any help.

Regards,
