Crash on startup

[skuizz]

Hi,

I bought the game on Steam several months ago and when I launch the game from the launcher, I have a white (yes... not black) screen and I have to kill the process manually (no error message). I tried to use the minimal settings but nothing changed.

My hpl.log is really short so I hope you will be able to help me

Version 1.20

Setting video mode: 1280 x 800 - 32 bpp

And that's all !

The weird thing is that I downloaded and installed a pirated version of the game after that and it works perfectly fine, even with the highest settings ! So I'm totally lost now :'(

My drivers are up to date.
Specs : Windows 7 64 , Radeon HD 7870, intel i5 2500k

If you need the hpl.log from the pirated version i will be glad to post it, if it can help you.

That's a very weird issue oO

Thanks for reading !

edit : i forgot to mention that I deleted the game in the Steam folder and the Documents Folder... nothing changed.
