It's because of the RSS wallpaper. When I install you themepack file, it asks to "Download Attachments" to setup and configure the RSS feed. The RSS feed will have to be configured on the computer first before it will work. Not sure about the screen saver unless it's part of the RSS as well.
The themepack would work automatically if it was just a normal desktop background image instead of one through a RSS though.
