[urvy]

hi,
here is the way i ad my add-on scenery
1) placing or unzipping it in the FS9 add-on scenery.
2) settings - scenery library - add area
3) selected the scenery - ok
4) close FS9 and restart
then i go to the go to airport , select add-on scenry and use the proper scnery, so farf no problem but when i closeFS9 and restart it the add-on scnery is gone.
after FS9 is closed i opened the FS9 add-on scenery and they were still there, what happened and how to correct it.
I tried several times to re-instal it but allways with the same result. Hellllllllllllllllllp

what scenery file are you talking about that is "disappearing"?????  next time, provide LINKS so that someone else can actually download it, and see if they can get the same results as you.
