I tried it! I did what you said but the steam restarted it self up and the game crashed like always!
Disable the Steam Overlay on specific games only by right-clicking on the game title, click on "Properties" and uncheck "Enable Steam Community In-Game" in the "General" tab.
Try this option and let me know.
It didn't work either! Looks like i have to buy a better memory card to my laptop lol!
