Gibberish instead of text (Mass Effect 2)

Text issues appeared after installing the mod for a romance with Tali for femshep. I'm guessing that the mod is English, and the game is in English. The same nonsense occurs in the message from Tali (though in normal conversations with her all right). What you can do in this case to fix the problem? And can someone tell me where to look for a Russified version of the mod?
