The only advice I could give you would be to do the Queen of Blowjobs events again, even when its completed, and further advance in other quests (for example Jessica's car events). My feeling is that this game moves on in its events only when all progress was made update by update. Also, carefully read the wt, even when you're sure to have followed it correctly...
For example, the waking-up event by Helena you mention did happen for me, but only after I was expecting it to happen, after I had done other events. But rest assure, it is possible to bring this game to completion (with final version downloaded on this thread at least).
