same here...a couple of days ago I get my launcher crashing after a few minutes...I have not installed anything of windows so I dont know whats going on??? The only thing I´ve installed is the new Tomb raider, now I cant play CoD
...will see if I have that update and hope that to be the reason because I have tried everything (reinstall Net 4, reinstall DX, deleting shaders directory, etc...) with no results...
