Aaaarrrgh!!!
Errata means errors, or, more specifically, a listing of known errors in a work--with or without their corrections. "Errata" does not refer to the corrections, except, possibly, in the context of them being included along with the errata itself. One does not "insert errata" or "include errata" or "use existing errata"--at least not in the sense that most of you are writing. One "corrects errata" or "removes errata" or "eliminates errata", or possibly "includes a list of errata". Or, more simply, "includes updates" or "includes corrections". Since, really, there's no need to include the errata, unless you are deliberately leaving the mistakes in, and even then, it's the included corrections to said errata that are the really useful part.
Learn the language, or don't use it. (and that applies on the individual-word level.)
