There are no native .txt files in this folder, and there shouldn't be. I just checked – both with the SoD and ND mod, and with the complete collection, I put the file in the folder, and it works perfectly.
Sorry, guys, I just figured it out. I installed the Russian translation for the complete collection, and now it works; before that, I only had the megapack installed. So, is it impossible to install the megapack? Could someone share which version of the translation they have installed and what works best? I understand that subjective opinions don't mean much, but I'm still curious about what the pros are using.
