Don't advertise it on the main page as having a trainer then.
The reason they do that is to show that a trainer is in production. That way people won't ask if a game is going to have a trainer before the game is even out. This is their site and they can do whatever they want with it. Don't like it, leave.
I managed to get past some crashes, by stop moving and let the automatic save finish then continued, or I just got plain lucky.
as I explained, if you have super speed on and move into a scripted trigger area (i.e. where it might autosave), the game may crash in those instances..
Game crashes for me with just the trainer activated, no options on. I sent you my saved game and config folders. I am in chapter 2 and game crashes when I follow Parker thru the door. If it doesn't crash for you then It must be my machine.
