Have reinstalled 4.15 and content - morphs not showing up

Ptrope

I've got a new PC and the first thing I installed was Studio 4.15. After I had made the mistake of using Daz Connect to install some content, I collated everything into a single directory, reset the database and reloaded the metadata, and worked with it a bit. Then I discovered that I had somehow ended up with a duplicated tree - the "Applications" folder was also inside the library and all the levels that followed it were there, too. I moved it back out to the main level, overwrote a few thousand files, again reset the database, and reloaded the metadata again. Now, none of my figures load with any morphs :-( . I've tried uninstalling Studio completely (why doesn't it show up in Control Panel?) and reinstalling it, but still the same problem. I'm puzzled. Flummoxed. Any suggestions?
