"Scenery file not found" ERROR

I have recently gotten a few file not found error when flying around my normal area (Baltimore, MD). 1. Is there any way to trace the file numbers given in the error message back to the scenery bgl file?2. How do you prevent this error from occuring?3. How can you tell what type of scenery file is missing? 4. The files listed in the error message appear to be in hex code. Is there some way to translate the file number to a scenery bmp file name?ThanksI'd Rather Be Flyin':-rotor
