Thank you, everyone. I am only able to use Macintosh programs. (No Windows, just the way it is.) I see that GMax is  available for all computers- as long as they are Windows. Doh!! It is an intrinsic part of the computer industry that the big companies do not have to bother with the little people, the minorities, those on the outskirts. This is a good time to punt open source software. Go GNU! I will keep trying to convert Max files, however, because it will be helpful and will benefit all of [cg] humanity.
