Scenery library problems

I've never had a problem with adding scenery but all of a sudden I cant get anything added.
For example Fly Tampa's Boston Logon I put the folder named boston containing the scenery and texture folder into the add on scenery folder.
Launch Fs9 click sceneric library, Add area, go to addon scenery, click the Boston folder Leave use direct checked. Then click Ok but it always goes into the folder showing the 2 folders inside.
But it never gets added to the list.
Any ideas.
