I know very little about the Mac solutions. I'd suggest a look at the Mac subforum, specifically at this thread, where there's a screenshot of a similar error in the very first post.
The Mac is indeed a machine that is very intolerant of error.
I'll try installing a copy of the pertinent sub-directory under the Alexander's Conquest directory, then reporting back on the results. If that don't work, then I guess I get to wait until Alex 2.0
Just remember, Windows was designed so you could mess with it; the Mac OS was designed so you wouldn't have to. In any case, thanks for writing.
