Out of the blue - "No Valid License" error. Why??

I don’t understand this. I’ve had Cubase for years and just used it the other day. Today it won’t open and it’s telling me “No valid license found. The program will now quit.”

What the…??? There hasn’t been a single thing that’s changed with my laptop. Can anyone tell me how I can get it to work again?



What Cubase derivative do you have? Pro/Artist/Elements/LE/AI?

If you use USB-eLicenser, try to unplug it and plug it back.

Thank you for the response!

I use Cubase AI 6.

I’ve always been able to open Cubase and use it whether I’m connected to the Yamaha amp or not. My frustration level right now is through the roof. Why would the license for this all of a sudden be a problem? I opened my eLicenser program and everything looks to be OK. I’m so confused by this.


Can you try to trigger Maintenance in the eLCC?

Could you send a screenshot of the right part of the eLCC window, or the whole eLCC, but blur your eLicenser Number?
