Scrool up and follow SlayerSTK's instructions and you should be able to play :)

Thank you very much for the infos :)
PS: If you start the game as mercenary you will crash, with an error regarding grenade launcher ammo so just locate trade_mercenary.ltx (usually in gamedata/configs/misc/trade) and change the string "ammo_m134_250" to "ammo_m134" . Hope this will help someone. Good game!

Credits goes to Firmament, i posted this solution here because it isn't so simple to find it without search with the correct "FATAL ERROR"

For those who crash trying entering Limansk for the first time, try to add in this path "Gamedata\meshes\actors\stalker_nebo" (located inside stalker directory) this file: Mediafire.com
Hope it will help someone and sorry for my bad english ^^
