Hi santos.
Do you have the freeware prog called DXT.BMP,it converts the bmps so fs9 can see them,its mainly used after you have done a repaint with a program like paintshop pro.
If you do have it then look at the bmp i stated in my earlier post,and check to see if they are saved in extended 16bit 565,one of these was in a different mode and caused the crash to desktop.
If you dont have the freeware DXT.BMP,you should be able to get it from avsim or flightsim.com.
It takes about 5 min to figure out how to use.
