Nitro Pro 11 deactivation / activation issue

[Stadt Oerlinghausen 0]

Hello,
We bought a total of 20 Nitro Pro 11 licenses.
To date, 17 of these licenses are in use.
Due to malfunctions I wanted to deactivate 3 of the licenses in use and reinstall them.
Therefore I created the deactivation key from inside the program.
Then I tried to deactivate Nitro using the built-in function.
However, the website www.nitropdf.com/de/activation did not ask for the de-installation ID but for the activation certificate.
Therefore I could not deactivate the program properly.
The manual deactivation via the website https://www.internetactivation.com/ECOSYSTEM/ActivationServer/tiactivate/default.aspx also did not work
I then completely uninstalled Nitro and used the Nitro Cleanup utility.
If I now want to reinstall Nitro, an try to activate it, I get an error message that the installation ID is incorrect or the license is already in use.
This cannot be because I tried to deactivate 3 of the 17 licenses in use and we also have 3 more unused licenses

Hello @Stadt Oerlinghausen

Thanks for reaching out to us!

I made the necessary changes to your key so that you can reactivate successfully.

I released your Nitro Pro 11 serial number so you can reactivate. Please get the correct version 11 installer from here.

I hope this helps. Let me know if you require anything else.

Hello and thanks for the changes to our license key.

But now I see that 19 of our licenses are in use. 

What about the 3 licenses that have tried in vain to deactivate?
