FSX transparent textures

After repainting several FSX aircraft I was surprised to see one of my repaints all of a sudden went transparent on me. Thankfully, I have a video-to-prove-that the repaint did show-up properly in FSX at one time.
If anyone ever figures out what the hel is going on with FSX, I sure would like them to inform me. I've had it for over-a-month and can't figure it out no how.
My repaint went transparent

EDIT:
O.K., I admit it . . . I'm an idiot!
I renamed the texture.cfg in the aircraft folder to see what would happen but forgot about it, We should all now know the texture.cfg file calls the requisite files from the main texture folder. Smiple? You bet.
