Hello , I have since my purchase the same problem that has been reported on this post .
I bought the license monthly and immediately canceled to buy full .
I installed via the control center , it remains in demo mode.
I tried with the offline mode, does not work and the link is dead until last updated (since the link works but I still can not activate sonar)
He has one month pending the response of the cakewalk support, sonar active magically , I was happy and able to work .
But for a good week without sonar reason is ironed in demo mode nor the control center or offline mode does work.
I'm in a bind, a project approach next week and my software not working ....
thank you very much
