klausfeldner Posted October 6, 2019 Report Share Posted October 6, 2019 (edited) Dear friends, in march 2019 I bought Nitro Pro 12, including the option for one year upgrade service. Now I got the information that I can upgrade to Nitro Pro 13. I can't activate Nitro Pro 13 with my Nitro Pro 12 serial number, I am told that it is invalid. Purchased on: 22.03.2019 RE-No.: AKD-**** Reference: **** What can I do or did I misunderstand something? Many thanks in advance. -Klaus- Edited October 7, 2019 by Leslie V.
