Unfortunately I've not had any luck with Crossover either.  (Still spent the
$15 in case further experiments get somewhere)
I'll see if I can pester cwdurst for more details over at the forum.

Since signs are pointing to this being a downloading/validation issue, can
someone please do a file-by-file comparison between a working install (say on
Windows) and what we get?

(Note: I don't consider the "patch" to be a feasible workaround.  Besides
legality, which is enough for me, I also want achievements and multiplayer!)
