Just tried a little experiment. Opened a project after a reboot and sonar crashed (as it's been doing for the last week and it was expected) Had to shut down sonar in task manager to be able to open the project and everything works. Removed all instances of CA 2A (hearing a lot of problems with this plugin but haven't had any issues myself but what the heck) did a save as of the same project without the plugin. Shutdown, reboot open the test project, sonar crashes, shut down in task manager and open sonar and the project loads without incident. So far so good. Go to file explorer any try to delete the test .cwp file and I was unable to do so. Dialog tells me it is running in sonar.....sonar had been shut down. Go to task manager and close sonar, try again to delete the file without success. It would seem that sonar stays running even if I do everything possible to shut it down. I had received a similar message when I tried unsuccessfully to roll back and was never able to roll back except by doing a system restore. Not sure what gremilins are involved but maybe some one here has an idea. Again, everything was rock solid before I updated to 2016.11. I'm back to 2016.10 but the headaches have followed me!

Something is up with the 2016.11 Release
 
1 - Have noticed I get the 'Add Track' dialog appear at Random times
2 - Seems to be some issue with Rapture Session. Although I didn't immediately get an issue,  I now get a crash on loading some projects (during the project load process, the bug reporter doesn't kick in). I did a debug and found that the error was:
 
Unhandled exception at 0x00000000328F4A48 (RaptureSession_64.vst3) in SONARPLT.EXE: Fatal program exit requested.
 
So I tested opening a blank project, and inserting Rapture session -  I get the same crash.
 
So seems an issue with RaptureSession_64.vst3 ?
 
 

Add track pops up just at/after a crash here as well...I've reported every crash via reporter

I was suffering the following problems.

1. Program freezing or crashing when opening a project.

2. Ik multimedia products related to amplitude were no longer authorized.

3. EZ mix from Toontrack was missing from the plug in list.

4. Some sonitus effects were identified as being missing.

5. Some East West files were sometimes loading and sometimes were listed as missing or unavailable.

My music computer is not normally connected to the net unless I am downloading or installing. So the latest update was certainly not the cause of my problems. Automatic updates are set to be at my discretion to apply. I did roll back my existing version but I still had the problems. Here is how I fixed them.

I authorized the IK multimedia products as required. Then I re-installed EZ mix. I confirmed that they were working. I had no idea what to do about the other problems so I thought I had nothing to lose by updating everything to the available versions through command center. To my great relief everything is back to normal.
Perhaps my experience will work for others too.

While doing all of this I did find that windows update is not working. I will fix that...... I hope on another day.

I just uploaded a mini dump for  CWBRN-61469  My situation is a little different. I've never updated to 2016.11, yet started having the same problem last week with 2016.09  Strangely even with old image files from Oct that I reverted back to.
 
Even more strangely is if I revert to my Oct image while not connected to the internet, my OS doesn't get infected with this runtime bug. 30 min after connecting to the internet, the image gets this runtime error bug which only happens after a reboot and opening the 1st CWP. Once it's infected every single time I reboot and open a CWP, I get the runtime error.

I saw some posts from the bakers regarding a fix but it seemed to be related to the CA-2A crashes only. I'm hoping all these dropouts, stutters, buzzes have something to do with this and that the fix makes it go away. Until this release, my system was really solid. I can't work on anything right now.

Yeah well, latest sonar, all i have to say is, sonar crashed while i was changing velocity on addictive drums while using step sequencer......So i filed the problem report......and now basically every time i try to reload that project, it crashes instantly and goes straight to problem reporter!!!

Inserted Chromaphone into an existing project.
Then went to edit >> undo insert synth and it crashed.
This (and the other problems that other users have reported) happened frequently since the update to 2016.11 so I did a complete system restore from a disc image as at 26th Nov and this crash happened using that system i.e. on Sonar Platinum 2016.10
 
Fault reporter then generated 183 minidump files for this one crash and I can’t upload all of these.
 
My system is now virtually unusable and I’ve given up! Hopefully a fix will happen soon

I've got the issue with the CA-2A reproduced and trapped - I'm working on a fix now.  Thank you for all of the information on this thread - it really helped to nail this down!  I'll keep you posted.

care to share? what was the issue?

I think there's more going on than just CA-2A issues

deffo, i haven't experienced any issues personally, but the reports are a bit worrying!
 
i'd still like to know what the issue was, we are all engineers after all
