In Poser 11,  I open  whatever figure or file  I want.   It comes from my Poser 7 folder (I named it that when I was using Poser 7).  That folder has over a 100 files, but I'm told that it's empty.   "If I'm lucky,"   a + (add library) and - (delete library) appear in the top right corner.  They don't always appear.  When I click on a + add file, it takes me to an add runtime window.  I can't find my runtime, libraries.    I'm told there is already a runtime by that name.  
The Poser 7 folder must be intact, because I can open an image (as I showed you) .  But the figure appears weird, white and grey.   
When I do a search for something, I can't open anything.   I'm told the Poser 7 Files folder is empty.  Confusing?  YES!   This is all from a desktop. I also have Poser 11 on a laptop.  I just don't want to lose it on the desktop.  Thanks!
