Didn't know that RS licences arent transferrable. I bought my C4D licence (R13) second hand with official licence transfer. Since than I continued to upgrade every year until R20. That is the last version I have.

Yes, I'm living in the EU, so it is legal to buy any software second hand.
RECTRO
Yeah, exactly. I have r20 and the last RS version from my maintenance.
Thanks for the answers!
