I received an email from Steinberg informing me to update, so I did. Downloaded the 2 files, Halion, and the content. Installed and ran the eLicenser maintenance.
But I get the attached screenshot grab when Cubase boots.
At this point it might be easier to just reinstall everything. Delete your “C:\Users{{USERNAME}}\AppData\Roaming\Steinberg\Content” folder and reinstall Cubase again using the full Cubase installer downloaded from the Steinberg Download Assistant. Make it reinstall everything.
You’ll get a different error message when starting up Cubase and Halion Sonic SE. Just click “Remove”.
I actually began that process immediately after sending my previous message. Of course, all is back to normal, except for my sound card driver, which I am about to troubleshoot now. Thanks for your help.
