I reinstalled all my previous content into the Vue 7 library, but a lot of objects won't show up.  When I try to open their folders it says that there is nothing to display in the collection and asks if I want to create a new collection.  I say yes and navigate to the folder the stuff is in and the colleciton comes up empty.  I can bring the stuff in if I browse to them and then open them, but they don't come up otherwise.  The same is true of materials and atmospheres.  I didn't have this probelm in Vue 6 Infinite.  What am I doing wrong?
