This should not be returned by Render... :-)
I've seen this being returned by both Initialize and Open calls - if
the AU won't initialize, then it shouldn't be asked to be rendered (and
the AUBase classes will not even ask you to render if you aren't
initialized) - in either case the host will see a problem... we've
suggested in the past that if a host sees this error code, that it
indicate to the user that they don't have the authorisation to use the
AU.
