Ah, fair enough, I thought you had a copy to verify on, my bad.
Still, I just tried several more times - and on the fourth attempt some options worked, some didn't, but the game didn't crash outright, only on close. Seems it's going to be hit and miss - on Steam at least.
OK, thanks for the info. We rely on members to let us know before we spend/waste money on a new distribution if current trainer already works. Will ask our trainer monkeys to confirm.
