Cockpit display problem!!

Hi all, newbie here.
Just recently purchased FS2004 and have got a problem with trying to display the 2d view cockpit in any aircraft.
The 3d view works fine but when I press the s key to change to 2d all the controls are blacked out. Also when I try to display the radio it appears as a black rectangle on the screen.
Any ideas would be appreciated to solve this problem.
Thanks
