XML Guestbook - "Error Loading XML"

I am trying to work with the .fla file that I downloaded from the tutorial. I download, extract all the contents and open the .fla. When I run it, it responds with this error. I searched the forums but no one seemed to have the same problem. Any ideas?

Error loading XML file
Error opening URL “file:///C|/Documents%20and%20Settings/Dan/Desktop/guestbook.xml?uniq=2974”

Secondly, when I try the guestbook example that his shown in the tutorial, when I click send the textbox becomes blank 0/1 entries.

I just want to make sure that other people are able to use this.

Thanks for the help!
