Cannot see out from cockpit seat! HELP!

I have Vista w/32-bit operating system. I recently downloaded corsair_f4u7 which is a great corsair war bird. Everything is fantastic EXCEPT I cannot see out through the closed canopy when the canopy is closed. Everything is black! However, when I open the canopy...behold I can see all surroundings just fine. In other words...the canopy of the corsair is black! When flying regularly viewing the plane from the outside the canopy is clear on every view and I can see inside the canopy at the pilot, guages, etc! What is wrong??
