Registration/download access error: X kein AC

if you bought a sealed cubase pro, that means you got in the cubase box a usb dongle also. The license is inside this. You dont have to do anything else, just plug the dongle in a usb port.
I suppose you got also an activation code which is of no use as you have already have cubase pre-activated in the usb dongle inside the sealed box you bought. All you have to do is simple register the usb dongle in your steinberg account.
The download is independent from any code itself, or elicense or whatever. you just run the download program and thats all. Just be sure you gave admin rights to the download manager

Ah ok…thank you very much for your reply I feel im closer to using audio warp!! I just couldn’t see any licenses from the usb showing up in the elicense software in the right hand side of the license pane. Nor were there any visible licenses in my registered products in my steinberg account. I get this after registering usb license:

Your eLicenser with the number 1xxxxx2 4xxxxxB was successfully registered.

Currently, there is no valid Steinberg product license found on this eLicenser.

When the usb dongle is highlighted, Synchrosoft license pane to the right of the GUI reads:

All Applications

Steinberg, Non-movable, Remaining time, 25h

then hovering over it I get a message that says Limited license (might expire)

So do I just download a trial from steinberg and then the usb dongle included in the packaging will facilitate full functionality?

Same issue here with Cubase Pro 10 crossgrade. USB e-licenser is registered in my account. The download access code is giving the error “kein AC” and I cannot get the license key until I have entered the DAC. Downloaded the 30 day trial while I find a way to fix this. Looking at other posts, this could be a server issue?

No. This is not going to work.
There are no pre-installed licenses on the stick. This must be downloaded. But that does not work.
Have the same problem with the error message “kein AC” which is German and means no activation code.
Therefore, think this is a license server bug and hopefully will be solved on Monday by the support.
Have until then the trial version with the activation code installed.

This is false. I also got the sealed Pro 10 Box and the the dongle is empty. License needs to be activated with the Download Access Code provided in the box. Maybe it used to be different. I don’t know.

Then your product you bought its not valid. Ask for a full refound.
The license is ALWAYS inside the dongle and you should see that when you launch the elicenser program

Hello! I have the same message with Crossgrade Version. X kein AC

Same problem here I bought Cubase pro 10 through US online vendor. X Kei AC. Please help 2 days of trying to no avail.


JFYI, AC means Activation Code.

Have just talked to the support in Hamburg. It is a bug on licensing server.
It should be fixed during the day, so that after this error message no longer occurs and the activation code is issued to permanent licensing on the stick to save.

yes I called them to and they said the same.

Problem solved. It works now! :slight_smile:

In my case problem SOLVED, I received Activation Code just minute ago.

Hi everyone,

Please excuse the inconvenience!

The problem should be solved now.
Please try again.


Yep ! Finally :smiley:

Pretty sure it’s valid. Bought it directly from Steinberg. :wink:

Yep got the download manager after the code is now being accepted. beginning download now///
thanks for heads up everyone

kein ac, German for “no account.” Server issues over the weekend, now fixed.


i bought cubase pro 10 but says that
All Applications

Steinberg, Non-movable, Remaining time, 25h

I try to reinstall the elicenser control, i do the mainteance but licens is still limited, why?


Hi and welcome,

Did you get a Download Access Code or an Activation Code?

If you got a Download Access Code, go to the MySteinberg and get an Activation Code.

Then in the eLCC application click to Enter Activation Code and type the Activation Code in. Click to Download the license.
