As per the title, if I try to run either don't starve or don't starve together, I get a black screen then the message "dontstarve_steam.exe has stopped running." I've tried reinstalling the DXredist and VXredist files with no joy. I have also validated the integrity of the local files. Previously (last year or so?) it worked fine.
I am running an Nvidia GTX960 with the latest drivers on Windows 7.
I own Don't starve, Reign of Giants, and Don't Starve Together beta, all through Steam.
There's nothing to reproduce, the game simply won't launch.
