That's odd - I have sold 31 copies of this and no one else had this problem. I went back and checked the download and it is showing up there and printing out. It must have something to do with your version of Adobe Acrobat Reader or if you are using a Mac. That accounts for 99.9% of printing issues. See below for more info:
1. Make sure you are using an up to date version of Acrobat Reader.
You can check the version by clicking Help then About from within
reader. If you have a version earlier than 5.0 or 6.0, you should
update your reader.
2. If you have a Mac, you may be opening it with a Mac program
called "Preview" and not even know it. Preview has documented problems
opening modern Adobe files. If you have a Mac, try opening Adobe
Reader first (rather than just clicking on the file), then open the
file within Adobe Reader. You may also choose to set the default
reader to Adobe Reader by following the instructions here.
To change the default reader on a Mac to Adobe:
Click on the icon of a PDF file type then choose File --> Get Info
You will see a dialog box labeled something like this "sample.pdf" Info
Near the bottom, you will see a section titled "Open With:"
That indicates what application on you Mac is the default.
Click on the pop-up to bring up the list of possible applications
and select Adobe Reader (whatever version is installed), then click
"Change All" to make it the default application for all .pdf files.
The OS will then ask you if you are sure, click "Continue."
Now the Mac will use Reader instead of Preview.
