GFionda 0 Report post Posted February 14, 2018 Hi, I received an email last week telling me that I needed to update my nitro pro, the update would resolve common issues etc. after the download was completed, Nitro has returned to being a free session and will expire in 8 days. I only purchased the package in September. Now I am trying to reinstall, however, it only brings up the free trial. I cannot find where the activation key/ serial number goes to reinstate my Nitro pro to the full package. Please help!! Giovanna Quote Share this post Link to post Share on other sites

Kelly Maynard 0 Report post Posted February 20, 2018 My Nitro Pro 10 that I own no longer allows me to open a PDF file using Nitro. I get this error message, "The service does not have sufficient privileges. Please re-install. I also cannot open Nitro as I get the same message, so I cannot obtain my license or PM so that I can re-install. Can someone help me? Thanks! Quote Share this post Link to post Share on other sites
