I got problems with CA-2A after the update 2016.11 and tested some VSTs in Adobe Audition 2017.
Here are some screenshots of the plugin scan in Adobe Audition CC
I got crashes with following plugins:
CA-2A
Rapture Session
Z3TA+
Melodyne 4.1

Melodyne 4.1
I tried to insert CA-2A : Adobe Audition crashed, but the program was still functional
After that I loaded the plugins again ("neu laden"), they worked again.
I started Sonar and everything was OK. It was possible to load CA-2A, no errors. I did a plugin scan in Sonar, no errors
After the PC reboot, Sonar crashed again, when I tried to load CA-2A.
It was interesting, that Adobe Audition could "repair" the plugins for a while.
Maybe this is interesting for the bakers to verify the problem of 2016.11. It seems that it is not only a problem of Sonar itself.
