jrmama42 Posted June 27, 2018 Report Share Posted June 27, 2018 I installed Nitro Pro 11 on my Dell Inspiron laptop (at least I remember installing it and using it for a while...). Recently I went to use it and it came up as "expired trial". I found the activation email, tried to enter the SN and activate, and it gave me a -23 Error: License Number Already Used Any suggestions on how to get the license to activate? I'm running Windows 10. Any other information you need? Link to comment Share on other sites More sharing options...
