Alden Reynoso Posted November 17, 2021 Report Share Posted November 17, 2021 (edited) I had an existing version of Nitro Pro 13 on my PC. It was working fine yesterday. Today, it will not open. It says in Task Manager that it is open, and on the taskbar it says it is open, but the screen will not pull up. I uninstalled and purchased a new license thinking perhaps the old one had expired. (I thought it was a one-time purchase?) Now, I ran the installer and it says it is on the machine, but still when I go to open it, it will not open. The little window on the taskbar says "expired trial." I tried to go through the Nitro Pro website to activate the license, but it keeps prompting me to deactivate even though it also shows no licenses are active. To be clear, I can't even get Nitro Pro desktop version to open so I can input a new serial number. Please advise. Edited November 17, 2021 by Alden Reynoso additional informaiton.
