When I said, 'original' I should said main or base package, but that is indeed the link I sent.  MicroCosm2 is the base package, and the other texture and morph packages can be applied to the meshes included with MicroCosm2.

Sample files were included in Poser 6 & 7.  I'm not sure if they were included in Poser 8 and later versions.
