Charlotte Stevens Posted June 22, 2022 Report Share Posted June 22, 2022 In March 2022 I paid for an upgrade which was not effected. I have now changed my computer and NITRO will not activate on my new computer and only shows in trail mode. When I enter the serial number says it does not recognise it. I have used Nitro Pro for many years and use on a daily basis please help. Link to comment Share on other sites More sharing options...
