I have Sonar Producer 8.3 (and 7,5,3) and it wasn't working with my new audio interface.
I'm not sure what just happened:
+ Last night I installed Sonar Artist demo to if it would work with the new interface. I tried to buy it today and realised the shop was closed and found this thread.
+ I followed the link to The Software shop above, followed the instructions and have Big Fish Audio Loop Content, Rapture Session, and SONAR Home Studio are added to My Products.
+ I tried an offline activation for
Artist and now it's out of demo and Membership: Valid through 2018-04-02 - Status Monthly. I can now save projects.
+ Installing and offline activation for
Home Studio and it's owned but it does say valid through 2019-03-03
I can work on my new project so I'm temporarily happy.
