Hi
I've been told by Arturia support that I need to have Sonar Professional 23.10.0 build 14 in order to run their soft synths. 
I'm currently on version 2017.09 (23.9.0.31). 
Command Center tells me that I'm on the latest version of Sonar (and I have the latest version of Command Center)
Any suggestions how to upgrade please? 

Thanks
Keith
