Renderotica

Hi all, just a question about installing content into daz. I just got the cock-o-rama core set and I've attempted to install it in the "my library" folder. I've extracted everything and manually put them in the correct folders (data, people, runtime). When I've looked through content library the meshes aren't showing up anywhere. This has also happened with some other content I have attempted to install, but not all. Does anyone know what commonly causes issues like these?
