Hello, sorry for not replying, haven't had internet all day. I mean, the storyline is that you shouldn't know what you need. Don't worry about it. This message (screenshot) was sent by the person you can meet in the first camera (at the end, the level with the computer).
Look, I take it you either have a bug or you're closing the game at the wrong time. I'm leaning towards the former. You should not have waited at all, there are two dialogues that last 1-2 minutes. Try downloading a new version. If after 5 minutes, this window does not close automatically or you have a black screen all the time, write again.
