ibb 0 Report post Posted December 6, 2018 I have been using Nitro Pro since May with no problems then the other day Nitro would not open. After restarting my computer I decided to uninstall and reinstall. I did this. Nitro still will not open. When I open Windows Task Manager it shows it is running CCD_00237.pdf Nitro Pro (Expired Trail). I tried help with activating Nitro pro is shows I have two licenses with zero activated. I am running windows 8. Please help. Share this post Link to post Share on other sites
