Some Installed Materials Don't show in Studio 4.9

in New Users
Installed MATerials that showed in 4.8 32-bit don't show in 4.9 64-bit. The items were installed by IM when it installed 4.9 and all my stuff. It's there in this directory:
Documents\DAZ 3D\Studio\My Library\My DAZ 3D Library\Runtime\Libraries\Pose\DAZ's The Kids 4\MATerials Kids 4
Is there a way to make 4.9 see this folder and load it?

It looks like you've got nested content folders -- you shouldn't have "My DAZ 3D Library" underneath "My Library" if "My Library" is the folder listed as a content folder in Content Directory Manager in DS.
Thank you Fixmypcmike, I'll try to fix that.
