Thank you Hagar, I've now got the DXT bmp and I now see the files.
The other links you questioned are the same ones I have, though I have cleaned all the previous ones out of my FSX Sim Objects, and reinstalled the `Express ONE` DC10-30 but the weird thing is that one of the planes I deleted is still showing, and able to fly and the thumbnail is still showing too

even though I did a search for all the DC 10's it doesn't come up with it anywhere. and the Express ONE is in my `airplane Sim objects, but that doesn't show in the FSX plane `Choices` when the game is started.
So maybe I'm on the wrong track here because it seem my original problem is caused by not having the correct FSX DC10-30 to work on :-/ could you suggest where I should look for the necessary info on how to remove all traces of this `Eastern DC10`please.
