Bad news, is that my version is not working with that crack. You should download the version from the cracker's name (google it) or if he willing to make a new crack for my version (I will provide the link).
Sorry to bring in the news, but this one just got updated again not too long ago. I'm not terribly interested in the game, so feel free to take your time to update it. 敗戦隷姫エルネア to v25.04.23
