llckalyn Posted September 7, 2021 Report Share Posted September 7, 2021 Hi, Recently i noticed that my Nitro Pro has reverted to trial mode when my pc upgrade the system. I have tried to install back my Nitro Pro 11 using my existing serial no & it shows bad parameter. Thus i had tried to deactivate & it failed as well. I had tried to upgrade this to Nitro Pro 13 & realized that this is only trial mode. I need help to advise how do i go about installing back my nitro with my existing serial no which purchased online. Link to comment Share on other sites More sharing options...
