I've downloaded maps before and done the exact same things I've done with the other maps, which work fine. It may be a problem with the way my computer downloaded it, now that you mention it. I've gotten object packs before and stuff has been missing from those. The thing is, nothing that should run the map seems to be missing from the download.
At any rate, it's probably my computer's fault rather than yours. I'll try again once my new machine is set up.
