Thanks for this. I see on that site that there are several files that start with my current build number (49922). Do I select the one that goes straight to the newest build in one go (49922-61388) or does it have to be done in stages? I see some are called Hotfixes and some are called Service Packs. Is there a difference?
Also from your avatar I see you have Trainz Driver on iPad. Are you experiencing the non-start issue after updating to iOS8? Auran recognize the problem and have sent a fix to Apple apparently. (I have Trainz Simulator and Trainz Driver on my iPad Mini but either show on my avatar. I'll have to look into that when I can open them again.)
