Maschine back to demo after updating mac

I've been making a lot of beats on the Maschine MK1, until i updated the mac i was using. After that i was unable to make the Maschine light up, and struggled with this problem for a while, but managed to fix it. Now the Maschine lights up, but when opening the software i get three options, doing a 30 minute demo, activating the Maschine or buying a new account. When I’m m trying to activate it in native access by using the serial number on the cd cover, I’m told its already activated. And if i try to use service center, I’m not able to connect to the internet, and as NA has removed offline activating i cant do anything. Is there anyone who knows how to fix this problem? All help is appreciated!!🙂
