language problem

Hi guys, i've recently bought this game from steam
i'm italian and also the game manual is in italian
but i don't know why the game starts in english

is there a way to change the language?

(SOLVED)
go in the game folder
...\Steam\steamapps\common\divinity ii - dragon knight saga\data

open the "language" file with the wordpad

Edit the first line:
<Language XBox="Default" Spoken="English" Text="English" />

it must be like this:
<Language XBox="Default" Spoken="English" Text="Italian" />
