I own this book, too, but I am not actively working in it yet. My copy
is the third edition.

On page 323 of my edition it says:

"You need to install both pygame and livewires before you can run the
programs presented in this chapter. Fortunately, versions of both are
on the companion website (www.courseptr.com/downloads) in the Software
folder. Just follow the installation instructions that accompany the
packages."

You mention that you installed livewires, but did not mention
installing pygame. Could this be your problem? Also, the author notes
that the livewires package that he provides on HIS site is a modified
version of livewires. If you went to the official LiveWires website to
download and install livewires, then it is possible it might not work
with the programs in the book. The author mentions this as a "Trap" on
the same page.

I doubt that your exact version of Python 3.x is a problem as long as
you have at least 3.1.

Another trap is mentioned on page 324:

"Just as with a program that uses Tkinter to create a new window, you
shouldn't run a livewires program from IDLE..."

The only other thing that I can think of is that you may not be
importing all of the needed modules. Check your code with the author's
carefully to see that you have done so.
