I had to reinstall Sierra from scratch after it would not display anything on my monitor (long story).
This meant having to redownload everything from Steinberg account to reinstall that as well, including a new eLicenser. I entered the activation for Cubase Elements 9, but it said it had already been used. So I went through the process of registering the new eLicenser, was able to activate Pashop and Zero Gravity, but now Cubase Elements 9 doesn’t even show up in my account!
It’s downloaded and installed, but asks for an activation code.
UPDATE: Contacted support, they sorted it out for me.
