Still getting crashes as well with trainer. I tried it with no cheats but trainer on and with cheats, but it crashes after i do i mission. I dont crash when not doing missions though. I can sit in town and nothing.
Have you tried the same without a trainer at all? I see TONS of threads on Steam forum where people report a crash occurring when changing levels / during loading screens. I have the feeling the crashes are caused by the game and not by the trainer.
