Crap I forgot Steam has to review and approve the DLC and they don't work weekends... Well, everything's done and submitted so I'll launch the DLC the moment they approve it.
I added the DLC files for download here as the DLC is free anyway. You still need to use the steam version but extract the 3 files here:
*your steam location*\steamapps\common\Monster Girl Factory\HCreatureCrafter\Content\Paks
and then run the game. I'll delete them from here once Steam approves the DLC
