Guys I found the solution.
All you have to do is download from the torrent, it will download a .rar archive, then you extract all in an empty folder, and you'll get an error message about some files being damaged, close this window like you dont give a sh*t, and go to the directory where you extracted the .rar, now you open the updater and it should download like 500mb or at least that was for me, and then open from the l2.exe from the system-en folder and it should work.
