Hmm, I am not sure what might be causing what you are referring to. By "forbidding you from entering the game from the menu", are you referring to the main menu with the saves listed? Or the secretary screen won't load a character on startup?
Right, this mod works with game version 0.04d, which doesn't have a start menu/saves. So if you see those then this mod isn't made for that version of the game. If you are using right game version, then it is either the files being in the wrong location or your PC's native language isn't English, which can cause mods to not work right based on a known bug.
