I've tried Firefox, Safari, both links provided by the author, FOUR different extraction utilities, and absolutely nothing works. I even cleaned up all the hidden garbage files that Stuffit leaves behind when it chokes on a file. Why the author would put this in a .bz2 archive instead of leaving it as a .dmg is beyond me. But if some kind soul wants to post a working dmg to rapidshare.com and share it with us, that would be a better than dealing with this ridiculousness.
