Hello, thank you for your trust and purchase, dear friend. 

It's enough if you download both Blender files(( VDM Blender & VDM Blender_ Single )) and extract them from the compressed state together; they will work easily. Please test again, and if there is any issue, do not hesitate to send a message.

You can also watch this video tutorial. Good luck.
