Good, that's fine.
What you're reading now is in a separate window to the email guide - it may even be completely hiding it at the moment.
This is really just a test window for you to play with. Try moving it around, resizing it etc. When you're bored with that (which shouldn't be very long!) close this window by clicking on its "close-box". On most Windows systems, this is a box containing an X at the far right of the windows's title bar. On a Macintosh, it's the box at the far left of the title bar.
