Interesting, since I appear to already have it (or some wacky version of it). Updated last night through SDC (around 7 or 8 PM EST). All components got an update.
GalCivII version: 1.50[b].101 with 1.50.100 now showing as available. hmm....
DA version: 1.59.078
*shrugs*
I haven't tried to fire it up yet, watch it explode when I do.
