Still in the review queue
"Your DLC is in the review queue. This review typically takes 3-5 business days and we will e-mail you with feedback or approval."
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
