Gianluca Landi 0 Report post Posted December 15, 2020 Hi. I have a Premium account but suddenly since yesterday every time I open a PDF it keep ask me to activate the product. The pop-up pretend to show me a certificate but there is no one. The system recognize me as Premium user but I can't really figure it out what to do... I'm attaching the "empty" pop-up. As well the link "gonitro.com/activation" doesn't work. Please help... Thanks Share this post Link to post Share on other sites

Could you please try the following steps then see if it will let you proceed with the activation? 1. Download Nitro cleanup tool from the link below:http://install.nitropdf.com/professional_13192356/install-cleanup/install-cleanup.zip 2. Extract the cleanup utility then run the cleanup tool by double-clicking nitro-cleanup.vbs. A command window will appear during the cleanup process. 3. After the cleanup, restart the computer. 4. Install Nitro Pro 13.31 by downloading a new installer from the link below: https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 13' link. 5.
