Be that as it may, someone else reported that this very error message went away, and the library started working correctly, after they had updated their Flash player plugin. Nothing else, just that. This information was not a guess, it was found on an internet search. Pffft!!

We have to assume, then, that the problem was resolved by something else they unknowingly did at the same time.
