I am unable to unzip the attached files in this tutorial. I receive the cannot open file error indicating that the file is not a valid archive. I have tried to download te files many times. Is there anything I can do to get these files? I really need an example like this.
Thank you


Both download and open just fine for me.

@Clzeigler what operating system are you using? What did you do and use to open these zip files?

its working in both windows Xp and windows 7
