Sorry - I've had a busy couple of weeks! My SM software arrived today and inspired me to have a good look at this!
Yes, I do speak Russian - I lived in Moscow for 5 years and spent two of them on language courses. I doubt my vocabulary can cope with anything too technical, but if I am confused by the way you are phrasing things I can get a better idea from reading the Russian. I am no translator, though!
Here is the first chunk I've looked at

I've reworked some of the phrasing it a little - if you would rather I stick more religiously to your translation then let me know
Let’s start teaching baby at home... All by ourselves... Hooray!
If you own the ‘Soft Mozart’ program, you have already begun to believe this is possible. All that is left, is to make it happen! The first step is the most difficult – this is because we are most afraid of making mistakes. Please, don't worry! With our program, it is quite difficult to mess it up. In fact, it is practically impossible!
Set aside a certain area in your home for music lessons. Hopefully, this place can be kept entirely for this purpose. Music education is going to be part of your household now, and in an ideal world your child should have access to our program all the time. It should be as accessible as their favorite games, toys or books. Therefore, if you have an old computer (so old that you already thinking of throwing it out), connect it to your keyboard or digital piano and dedicate this machine entirely for music lessons. Our software doesn’t require much memory or extra gadgets. Even 10-year-old computer could work well. If you do not have such a computer, ask your friends or relatives. They may be very grateful that you can help them to get rid of their ‘piece of junk’ or ‘dust collector’.
There is no need to follow the lesson plan religiously. We created it simply to give you a general idea of how it works in principle and how everything is generally structured. If you are not following it perfectly, it doesn’t mean that life is over! So long as you are progressing in the general direction of the lesson plan you are doomed to succeed – sooner or later. The rule of thumb here is to have as much fun as possible during the process of learning and maintain a regular practice schedule.
Do not ever compare your results with the results of other people. There is no need to cry: «Оh my, we are so far behind!» When you are learning music, your initial progress might be fast or it might be slow. I have heard many stories of people who have started very slow and then found their footing and progressed so much that nobody and nothing would dare to stop them. The goal of your learning is personal growth. The program is built for you and you are competing with nobody, but yourself!
