Why am I getting "CA Headless has encountered an error" suddenly?

Question

In the past few days, when I am in Elements Organizer 9 I get this message.  I'm not sure what damage is being done, Organizer, Photoshop Elements and Premiere Elements still seem to work OK.  However, when I tried to back up my Organizer catalog today, I got an error message part-way through and the backup terminated, and about the same time (I was multi-tasking and didn't see when this happened) I got another CA Headless error message.
What exactly does this mean, and what can I do about it?  And why is my backup not working?
And why can't Adobe engineers write error messages in plain English that mere mortals can understand without having to scratch their heads (no pun intended) and slog through forums and help menus to find out what the bloody error message means?  This error message is utterly useless to me, and I'm not stupid (I earned a PhD 40 years ago, though not in software engineering ...)  This is NOT helpful.

Answer 1

Unfortunately the CA Headless message re-appeared today.
I launched Elements Organizer 9 and left it open, planning to return to it after doing some other things on my computer.  Neither of the editors were open.  After a couple of minutes, I noticed the error message.
I hadn't actually done anything yet in Organizer, other than navigate to a specific album.  However, I should perhaps mention that under Edit>Preferences I had set Organizer to auto-analyze media when the system is idle.  The album to which I had navigated contained some new video files that I had added yesterday, and there is no evidence of any analysis having been done to them yet (no purple tag on the corner of any of the thumbnails).  So I suppose it is possible that the auto-analyzer had started to run once the system was idle and generated the error message.  I can't think of anything else that Elements 9 could have been doing that could have triggered an error message, once I'd opened the software and navigated to the album I wanted.  The error message appeared "behind" the Organizer screen, I didn't notice it until I Alt-Tabbed to the desktop.
I haven't actually started any editing of video files yet, will do so probably later today, will report any problems encountered.
So far the CA Headless message is no more than annoyance.  Haven't tried backing up the catalog again, but no need for that as nothing in it has changed since yesterday.
LATER IN THE DAY -- I've spent most of the afternoon editing and combining about 15 video clips in Premiere Elements, with Organizer open in the background.  The software seems to behave normally, and I haven't had a repetition of the CA Headless error since opening PrE and beginning work on the video files.  Whatever this problem is, except for the catalog-backup issue resolved earlier in this thread, it doesn't seem to be affecting the software in ways that matter to me.  If problems return later, I'll re-open this thread, but for now I think it's answered as much as it needs to be from my perspective.
