I have Cubase LE AI Elements 10.5 installed on the computer and I bought the “Steinberg Cubase Pro 11 Upgrade AI”. My 10.5 license is already on the USB dongle and now it comes in the installer that there is no upgradeable license:
I suppose so, but didn’t you say you already bought that? I don’t understand what’s happening there. All I can suggest is to make sure you have the latest ELC, which I suppose you do, since you’re using the Download assistant.
