I purchased monark recently but now it says in reaktor that my trial has expired, any solutions?
If you do not have the full version of Reaktor, most official ensembles have a 30 minute limit. After that, it shows demo message.
Check here the differences between the Reaktor free player and the full version:

If you have purchased Monark, then it should work using the Reaktor Player without requiring a full Reaktor licence. If that isn't working, you need to open a support ticket with NI.
The 30 minute limit with demo message is for using full reaktor with edit mode, and access to user ensembles. 'Powered by Reaktor' Stuff like Monark and Super8 should work with just the Reaktor Player.
