Glowing C152 night textures

Hello all, I purchased the Carenado c152 II and it is a joy to fly. But at night, the airplane textures start glowing bright blue or pink and black squares surround the gauges. I also noticed this problem only occurs when the interior night light is on. The textures and gauges turn back to normal when it's off.Btw I have fsx sp1 and a very poor graphics card. :(
