Commander, Engineering Corps
Just downloaded the 6.2 version of the game, but when I attempt to open it, I get this:
I'm currently on a Mac, using Yosemite 10.10
Ah, that's lies, terrible lies and videotapes. It's not actually damaged, I just must have messed up the code signing. I'll upload a new version soon, but in the meantime you can make it work by turning off or downgrading Gatekeeper.
Did this get fixed for you in 6.2.1?
Huzzah! It is indeed fixed.
