That's very odd. The only game crashes I have ever had have been from early versions of the game, or from misediting save files. I personally don't recommend editing save files unless you have lost everything and are trying to recover.
I have quite a few save files available, including several from my tutorial/walkthrough. I have files from days 2,4,5,9,12,14,15,16 and 19 - which is where I ended the tutorial. I have a number of files from later times as well, such as days 21,31,37,39,42,47,49,51,61,65, 74 as well as a few for specific circumstances - such as the Tony ntr route which I played as a matter of completeness.
I'd also suggest getting used to restarting. Also get in the habit of having more than one save file so you don't lose too much time.
