Here's what it says in the setup instructions you linked to

Installing the script

For RaspBMC/Raspbian/Debian distributions (Xbian as well, omit the word sudo), type the following and hit enter after each line:

1. sudo wget http://files.mausberrycircuits.com/setup.sh

2. sudo bash setup.sh

3. sudo reboot

Try again using the URL in step 1.
