Hi Matthias,
I just bought upgrade license from Elements 13 to Artist 13, but when I input the Download Access Code into Steinberg Download Assistant, it shows error message “You entered a Download Access Code for a product upgrade but you do not own a license to which this upgrade can be applied.”
I have checked my product license in Steinberg Account, it says that I have Cubase AI registered there, although I have bought an upgrade license from AI into Elements 10 on 03/06/2019, and I already get the upgrade from Elements 10 into Elements 13.
I have checked my Steinberg Download Assistant, it is written on the list that I have Cubase LE AI Elements 13.
So what do I have to do to solve this problem?
