referring to the walkthrough 7-0.txt
Hmm, I may not be able to help you then, unless you send me your save file.
The problem is that the game has several events at each level (for example, there are 70 events in Level 7). These are numbered within the game in some random order (probably in the order that the dev came up with the ideas for the events). When you play the game, you can trigger the events in almost any order. That is, the first event you play could be event 15, for example, followed by event 29, and then event 1. Sometimes (actually, usually) you have to complete one event before you can start another, but in general you won't follow the events in the exact same order as another player. More precisely, the events are grouped into threads, and the game forces you to follow each event in the tread in order, but you can follow the events in the other threads independently.
The walkthrough has the events numbered in the order that the person who wrote the walkthrough (which was not the developer) found the events, so his event #1 is actually event #28 in the game.
As a result, when you say you're stuck on event 30 (according to the walkthrough), I have no way of knowing which actual game event you're talking about. I did take a look in the game to try to figure out which event is triggered at 19:00 in the master bedroom, but none are, so the walkthrough may be out-of-date.
I suggest you install the walkthrough mod and it'll tell you want you need to do to get all the remaining events in the level (you can uninstall it or disable it when you've finished the level if you don't like it). It'll tell you which events (according to the game's numbering scheme) you're missing to complete the level, and I can help you figure out how to trigger the missing events.
Note as well that there's an issue in the game that, depending a choice you made in level 1, it may not be possible for you to complete all the events in level 7. If you send me your save I can tell you want you need to do to get back on track.
