First, don't double-click on pz2 files from explorer. It doesn't work. It only ends up reloading the default scene. If you want to use explorer, try dragging and dropping instead.

However, those files you posted are the wrong ones. Those aren't the ones that should be in the library. Those are the files that the morphs you want will reference. If you notice, those files have no thumbnails. those should be in \Runtime\Libraries\Morphs\StudioArtVartanian\MarinaMorphs\ not your poses folder. Look at the read me for the files you want in the pose folder. They all start with a number or an !.

You can try to move things around manually, but I recommend deleting everything and then using the purchase tab and letting poser install this one for you since there are a lot of files that need to be in the runtime, but not in your usual library folders. Then go to the purchases runtime in explorer and drag everything to the runtime of your choice, keeping all the paths intact for any of the extra files, like you would for geometry or texture files.
