Every time you close down Illy, the current preferences (which may have been changed while you worked on files) are saved, and every time you start up Illy, those preferences will be used.
Usually, preference corruption probably occurs randomly, caused by the OS, but if something in your files change the preferences to something that is not viable you will get an error like that.
You may press Cmd+Option+Shift during startup, which will replace the current preferences with the defaults, and probably you will get rid of the error message. It is probably not a cure, though.
If the error is persistent, the cure would be to get rid of the offending things in the files you work with.
Jacob, thank you kindly.

Really? I only have preference corruption with Adobe apps on both Windows and Mac. I’m not saying you’re wrong (mister using-an-eight-year-old-version-of-Illustrator), but can you back that up?
It is worse than you think, Scott: for word perfecting I use a ten year old version, to be able to use the twenty to thirty year old keyboard shortcuts; the youngest member of the power tool family is about twenty, and the oldest were born between the wars (the two big ones), as are the most important hand tools and measuring tools. We did switch to colour TV almost fifteen years ago, taking over a beauty now in her mid twenties, almost as old as the stereo set from the same fine family. And I never got the (high angle) grip of the ball pen.
And no, I cannot back it up: what I am saying is purely hearsay, merely repeating what Len said about the subject way back in the days of the fair forums.
You are welcome, Shenzi.
