I suspect Steinberg (Yamaha) has a record of your license. E-licensers do fail. Can they not look up your license and provide it for the USB dongle? Then start process over?
The same thing has happened to me, Bewitcher has disappeared, Granular Symphonies and a monton of libraries. This migration thing is a complete disaster. I can’t access almost any of the bookstores I had bought. I’m very angry at Steinberg.
