Official Nitronaut Leslie V Posted September 19, 2022 Official Nitronaut Report Share Posted September 19, 2022 Hello @glenn holt Thank you for your message - I can help you out. We have upgraded our activation servers. Please install the latest Nitro Pro 12 update (12.16.9.574) so you can reactivate successfully: https://www.gonitro.com/nps/product-details/downloads Then activate with your Nitro Pro 12 serial number. I hope this helps. Let me know if you require anything else. Link to comment Share on other sites More sharing options...
