CS6 Crashes When Saving Anything

Question

Today, FNAR, Illustrator CS6 began to crash on save.  It does this when saving to .ai, .pdf, .dwg...every format I've tried.  I have installed two new fonts, but that was a few weeks ago (and I have used Illustrator since then), so I don't suspect them first off.  I would think if that were the problem, the issue would have started immediately.  This has happened with other things running (Sketchup, AutoCAD) and with nothing else running but the usual background stuff.  I tried deleting that pesky. plist file, too, but could not find the directory it supposedly resides in anywhere on my PC. I also don't think it's a Creative Cloud user account issue, because to my knowledge I don't have such an account (corporate / business license here).  In-house IT's solution is: reinstall Illustrator (but that's almost always their solution to anything).  Meanwhile, if it is worth mentioning, my other Adobe products (like Acrobat XI) work fine.
I'm a pretty basic Illustrator user, so I really don't know what else to try.  Hoping someone has suggestions...

dluns,
Should it not be updated to 16.0.5?

Apart from that, you may try the list.
The following is a general list of things you may try when the issue is not in a specific file, and when it is not caused by issues with opening a file from external media, see below. You may have tried/done some of them already; 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save current artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to at least 5 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible), for CS3 - CC you may find the folder here:

5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall (ticking the box to delete the preferences), run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.
