Just to make sure, Launch Cakewalk Command Center. Select Sonar Platinum in the list and hit the "Launch" button. Does Sonar still fail to authorize at this point?

Thanks Freex I have tried that, Dan I have always launched Sonar Platinum within CCC by pressing the Launch Button since the Demo Mode I have also tried to launch Sonar directly using the shortcut on my desktop both were run as administrator. I have since tried to run the offline activation I get an Activation Response and put that into Sonar and nothing happens.
 
Again thank you both for the help

Please try closing C3 before launching SONAR.  
Let us know if that is able to authorize.

what is C3? 

C3 = Shorthand for Cakewalk Command Center.
For reference, on investigation this specific issue turned out to be billing related. So its was in demo mode because the current membership was not valid. Support will work with him to resolve his billing issue.

Just thought I would respond.
 
Firstly I would like to say a massive thank you to the community and the Staff members that helped me I'm new to Sonar but if the service/help I have received is anything to go bye I am going to be a happy customer for a long long time.
 
A quick explanation what happened: Basically I'm new to Sonar so I decided to go with the subscription model and give it a try for a month. I purchased a monthly subscription and decided straight away to cancel the subscription (I thought I was cancelling the automatic Renewal) to ensure I didn't get charged at the end of the month in case Sonar wasn't for me and I forgot to Cancel. Anyway this lead to the service being immediately stopped (put in Demo mode). I assumed I would have the full month to play around with Sonar as I had paid for it but this is not the case.
 
The solution: If you decide Sonar is not for you then wait until the last possible moment to cancel your subscription. If however you are reading this and done the same as me (like anyone but me would be so stupid) then the solution is to speak with Customer Support 
 
Again thank you all for the help. Talk Soon

Are you using Cakewalk command center ?
Try logging out / then logging in again.
Registration heavily relies on Command center log on.

Hi,
 
thanks for your response! Yeah, i used c3, run win as an admin and tried offline activation...sonar still runs in demo mode.
