so i just launched sonar and am met with a popup:
 
"This beta version has expired.
Please destroy it, in accordance with the terms of your Beta Test Site Agreement.

Thanks you."

I have steam edition, version 22.12.0.12... i've posted over there but wondered if anyone here had any clue?

I'm getting that same message (twice) when I do a VST scan in Sonar.
 
I have no idea to which program it refers. It would have been nice if whoever programmed that message had specified this.

Are you using the Sonar Steam edition ?

my solution was just to update to the latest version http://steamcommunity.com/app/380080/discussions/2/135508833657296655/

I really don't know if I'm using Sonar Steam. I AM using Omnisphere, which uses Steam.
 
 

OK, I googled Sonar Steam, and I can definitively say I'm not using Sonar Steam. 

then i think cakewalk need to confirm whether this message is coming from their stuff or steam's stuff
