Walkthrough for "The Arrival"

This walkthrough assumes you've read the instructions 
and are familiar with the user interface.  The data
disks that are found along the way have yellow tabs on
the right side.  When I refer to data disk 6, it means
the one with 6 yellow tabs on the right side.  I have
not included solutions to puzzles because the help in
the game is so good.  Hope this helps!
