Activation code missing

I purchased on the 25th nov 2020 2 licenses of |ManyCam Studio Lifetime !|. I have it installed on 2 PCs and on the second one, I’me asked to enter an activation code I never received.
I need to unlock all the features on my device LAPTOP-LU2HN3BJ_2
Refreshing doesn’t work.
Thanks a lot in advance!
