Do you have a cr2 editor? I would open the pose first, to see if it uses PMD injection, then verify that the path is still valid, if it does. If it doesn't use PMD, I would check your remapped M4 cr2 to make sure it contains the necessary injection slots. Or has the Poser Team fixed morph injection so we no longer need the blank slots? I don't remember.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
