For Leslie V, I just received an invite to upgrade from Nitro Pro 13 to Nitro Pro 14, which was supposed to be included free in my Feb 2022 upgrade via Cleverbridge.  Then, conveniently the upgrade was launched after the 1 year timeframe.

I cannot even get the 40% upgrade promo to accept my serial #.  **************  (Please obscure this)

It would be great if you could honor the originally promised free Nitro 14 upgrade

Thanks for reaching out to us! I am happy to assist you.

On the web page, please enter your serial number and follow the provided instructions. This will enable you to obtain a new Nitro Pro 14 serial key along with the necessary installation files.
