Curt Robinson Posted March 10, 2021 Report Share Posted March 10, 2021 Hello, I've tried to activate a license for Nitro Pro 12 on a new computer. I've deactivated all my licenses and I'm getting a "-23:Error - License number already used" when trying to activate. I've tried deactivating my anti-virus, but didn't help. What are next steps? Thanks, Curt Link to comment Share on other sites More sharing options...
