In my case the errors that do not let me continue with the game started in a scene with Rita and the mc in the Lecture Hall, when Rita sends a message to the mc to see her in the University Laboratory after I failed the attempt to access Ivan's laptop using the memory card together with the camera and the usb cable.
I also didn't install the mod, which is said to corrupt game options, I guess because it doesn't contain them. That it contains texts in Russian also happens with the other translations that the game comes with (as in previous games of that dev.), where if you choose another language other than English, usually appear texts not only in Russian (which I think is the native language of the developer and are part of the original scripts), but also in English. And I'm also waiting for someone to upload the bug-fixes version to continue playing where I left off.
Edit: If you install the
Walkthrough Mod (which is not updated), not all options appear in the shop with Lia, as it overwrites scripts from a previous version of the game.
