Did you make sure you got the entire contents of the "code" custom property copied over into your new file? The custom property called "code" actually contains about 20 or so lines of VBA code. Only one line shows at a time in the Custom Properties dialog.
Alternately, you can delete everything in the example file and create your own geometry. Then all you have to do is edit the custom property "NameOfSketchWithText" to whatever sketch you put your text in.
