Nvidia video card problem.

Hey Guyz! I just got a new Video Card its a Nvidia Geforce4 MX 440. When I open my flight simulator 2002 I get this message:
Safe mode has been enabled because your system is currently unable to use hardware acceleration. While in Safe mode, you will be able to run Flight Simulator and troubleshoot hardware issues, but performance and display quality will be affected. Product Support Services does not support Safe mode. For more information, see the Readme file, which is available from the Flight Simulator link on your Windows Start menu.

Does anyone know why my video card does this?? please help! Thank You
