The file "Graphics.zip" contains the graphics (moon phases, sky conditions, etc.) used by the calendar generators. Unzip them to whatever directory you want. However, make sure you change the variable "GraphDir" to point to where you put the files. You'll find the variable near the top of the file, in the section labelled "Constants". Substitute the path to where you put the files for the default (which should be "C:\TableSmith\Graphics").
