game does not launch

[ArthurBarbaro]

Same problem here. Launcher opens normally, checks login/password and updates normally, but when I click "Play" it opens a new window, both windows close, and that's it. No error messages.
I don't see any logos, options, nothing — the game window just opens completely blank (black) and closes half a second later. I don't even get to see it impacting on the cpu usage.
This started after the Dawntrail update, it worked normally before.

I'm playing from Steam, on Windows 10, using NVIDIA GeForce GTX 650.
I have tried restoring system settings and restoring game data (from the Launcher). Have not tried reinstalling the whole game yet.
I've also tried updating my graphics card driver (nvidia geforce gtx 650), with seemingly no difference whatsoever.

Does FF14 create any log file, anywhere? Couldn't find where one would be located. Is there maybe some config file option to force one to be created?
Thank you.
