Ok, Dave. I've played From the Meuse to the Rhine for about 3 hours now, with a CTD roughly every 5 minutes, but I cannot for the life of me get one to repeat from a save. I've honed it down so that a few times I've saved right before the action that prompts the CTD, but when I load up the save it will not repeat at all. I have no idea what to do. The saves do not take a snapshot of where you are, exactly, it seems. So if I save with a unit selected, for example, then when I load from the save the unit is not selected when I start, which means that in order to give it the command that caused the crash I have to first select it (again), so the saves are not, in other words, capturing the exact moment before the CTD, and cannot, because there is nearly always a unit selected when I get a CTD, but there are no units selected when I start from a save, even if I saved with the relevant unit selected.
I'll keep trying, but I'm gloomy about it. That scenario is unplayable for me, unless I save, literally, before every single order (and, actually, that's possible). Many others might be similar - I haven't really tried too many yet with 257. I'm just hoping someone else will be able to get a save for you, or that it vanishes when you fix other things from 257.
