First thing that came to mind when reading your reply, rhwalker, was that you didn't do much but reiterate each of my issues. I also get the idea you have absolutely no idea what your talking about, the latest driver update for Retrospect 6 (for Macintosh) was May 29, 2009. Unless you're only three months old that is not "a long time ago".
I would argue that Retrospect 6.1 is still viable software. You can buy an entire operating system for what it cost me to purchase, I expect some support for my patronage.
