I am Getting an error "Error 1242 Can't Open Video Device"

If you receive the error "Error 1242 Can't Open Video Device" you need to adjust your screen resolution.  Most of the time you may need to lower the resolution to 1024 x 768 in the Display Settings.

Right Click on your Desktop.

Left Click on "Properties".

Left Click on "Settings" tab.

Adjust resolution to 1024 x 768 then Left Click "Apply".

Retry the MMP to see if problem is fixed.

Also be sure that the resolution setting within the MMP Control Panel is at 800x600 and the CPU usage is set to 30 or lower.
