Hi @Francesco Caserta,

Thank you for reaching out to us through our Community Forums!

Version 12 and older licenses were upgraded to use with our new activation servers and Nitro Pro build. 
Our activation servers for older versions of Nitro Pro were retired, thus any new activation or deactivation attempts on these versions will no longer work. 

To continue on using your serial number, please install Nitro Pro by downloading the installer from the following location: 
https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 12' link

Once that specific build of Nitro Pro 12 is installed, activate it by going to the Help tab > About Nitro Pro > Activate. Enter the serial number then click on Activate.

Kind regards,
