Aquitaine 0 Report post Posted November 24, 2018 Updated Windows 10 to the latest build (1809) and the Nitro Pro activation was no longer valid. Went to the activation portal and deactivated it. It now shows zero of two allowable activations. Trying to activate Nitro Pro from activation button still shows -23 Error: License number already used. Waited thirty minutes, updated to the latest build of Nitro Pro 12. No change. Share this post Link to post Share on other sites
