serious Sam 3 won't start up

[Capricorn]

As of this morning, SS3 won't boot up. When I try to launch it from Steam, it'll bring up a black screen and then I'll hear an error report telling me that the game stopped working. It doesn't tell me what the error is and it was working just fine yesterday.

My computer specs:
Processor: Intel(R) Core(TM) i5-3550 CPU@ 3.30GH.z 3.70GHz
RAM: 16 GB
Graphics: AMD Radeon HD 7800 Series
OS: Windows 10 or 64 bits , processeur x64



Anyone else having this problem? Anyone fixed it?

and i missed two files :
Sam3.log and Sam3.rpt

If yeasterday it worked fine and you didn't install anything in the meanwhile, try to restart Steam and/or reboot your pc and try again, sometimes it's just that easy.

I did it . I even uninstall and reinstall steam it did not work

It's probably some OS update breaking the driver or similar. So, it doesn't create Sam3.log file?

[Capricorn]

no :/

I have the same issue. No log file created. I've re-installed twice, I've checked game cache... nothing works. Very disappointing.... and after trolling the internet for hours I still can't find a solution.

This sounds super strange. Normally, if there's no log, it is usually (like 99% cases) Steam cache being broken. That is easily checked for by installing a new fresh instance of Steam client in a new folder and downloading the game there.
In the rest, it would be some very early crash before the log is created. But in that case you wouldn't get a black screen. Log is opened before GPU driver is loaded.
