I have downloaded a few 3d models from c4dzone.com and when I opened these files in c4d, I see the below message. Can I use them in my Youtube channel videos?

This file was created with an Educational License of Cinema 4D.
It cannot be used for commercial purposes.

Not working for me in R23. Checked the Extensions menu but Birckgen is not available there.
