Crashes when launching game

I purchased this game previously (from another vendor), played it flawlessly and enjoyed the hell out of it…but updates weren’t available. That’s when the version log note “Updated to support NVIDIA 780M in newer iMacs” caught my eye in the App Store. Paid my $20 (again, I might add), downloaded the game, and it’s a crash salad. Shows the opening splash, then craps out.

Not acceptible, Feral. Not acceptible at all.
