I obtained the file by clicking "Request turn resend". A few minutes age I got an email labeled "turn 40" but in fact the attached .trn file is for turn 41.
Ooh dear. No no, don't use the one from the resend. I've made it so that won't work if you try again now, that's not the correct turn. I'm kind of relying on you having kept the original "turn 41" that was actually turn 40. I hope you all still have it.
