Apparently, the integrity of some files in your copy of the game is broken, when switching from Russian to English in the quest log, as well as in the game itself, there should not be any errors and phrases about damaged files. With the 3rd episode there are no problems, if the player does not try to play with mods or in a compressed version.
And judging by what is written on your screenshot, your copy of the game is probably modified by the 3rd party. So you shouldn't be surprised by bugs and errors.
