Lesson 1.7 travelling on schedule

[code][/code] I have the downloaded version of Rocket Spanish, I'm on 1.7 Travelling on Schedule. In it they discuss numbers and tellign time and explain that they wont' go into telling time here on the download and to refer to lesson 1.7 of the book.. well I got the donwloaded version.. why would they tell you to refer to a book if you got the downloaded version?

The three books can be downloaded in lesson 10, MegaSpanish bonus games and extras. There are 3 pdf files there which contain the three books. I took me awhile to find them also, but they are very good.
