If you have already entered the activation code, then your eLicenser dongle should have been updated with your new license (i.e. Cubase). You should be able to see that license if you open the eLicenser Control Center app.
If that is there, you don’t need to enter your activation code anymore to continue downloading and installing and using all of the other parts of Cubase.
To clarify - the “Enter your Download Access Code” field of the Steinberg Download Assistant is always in the first window, even when you don’t need it. You should just be able to click to Cubase and from there to the version you are licensed for, and go ahead and download, install, etc.
Still having trouble. When I try open Cubase it says “No valid License found. The program will quit now.”
I used your previous instructions of going into the eLicenser Control Centre app, but when I copied in the Activation Code is said " The Activation code has been used already. An activation code can be used only once to download or upgrade a license. Please contact your software vendor to get a valid activation code."
I’m trying to do that now, and my general aptitude may not be helping me so much, all I’m really good at is throwing my patience at things…
