I have been trying to upgrade my pc to windows 11, unfortunately i have had a few failures during the process. I t now says that i have activated some of my licenced products too many times, do i need to contact support to re activate once i have finished messing about.
I guess you are using a Cubase release that has Steinberg Licensing, you did not mention the release.
In that case just login to your Steinberg Online Profile and there you can deactivate the licenses yourself. After that you should be able to activate the machine again.
