I have more files of that nature from 20/1/14 also. So if you need them please let me know and will upload them straight away.

anymore news on this as the game is unplayable due to these crashes

Try:
Reinstall drives to beta (suggesting use geforce experience) in "clean" mode and don't uncheck physx etc.
Verifity files.
Game works now for me :)

Also gamerOSD causes crashes (if you have it. Its also with smartdoctor)
