Alexander Atanasov 0 Report post Posted March 6, 2019 Hello, I'm new in my company. I can find my invoice for Nitro Pro 8, but I've been using Nitro Pro 9 for the past year. Was there an free upgrade from Nitro Pro 8 to Nitro Pro 9 product back in the days? Thank you, Alexander Share this post Link to post Share on other sites
