what is interesting - when i add manually the scenery to the folder - it shows up - i quit FS - go to the scenery.cfg file - open it with word and the added new scenery is not showing
This is what you said yesterday: the scenery is added, but FS9 is not saving the setting. Also, I really hope you don't *save* it back with Word! That would CORRUPT the scenery.cfg!! You should never, ever, use Word to edit a text file. Use a proper text file editor, or at least Notepad.
Also, keep in mind there are TWO scenery.cfg files, one under the main FS9 folder, another one in the %APPDATA%\Microsoft\FS9. Depending on the OS and the permission settings, one or the other is used so, you might be fooled into thinking the scenery is not there, because you are looking the wrong file.
Try to remove BOTH scenery.cfg files, and reinstall one of our sceneries and NEVER open them with Word again!
