I did that Mr. Zippy and still got the same Scenery Library as I had before. It shows all the ORBX stuff and the original things for FSX,but none of the over 200 other sceneries I have added. When you look at the "Scenery library" it shows a number of things I have added but zero from the add on file titled (scenery) which is where all these files sit. I hate to do another install, have already done about a hundred of those from the disk, from STEAM, been using the simulator since 1998 but this one has me stuffed and I don't know what caused it. I didn't do any system tweaking. Knitting might be the next option.
