IF you're running Windows 7 (which a new computer should be) then the O/S will recognize Winzip files without having to install the program Winzip. Just a matter of double clicking on file then the O/S will open the Winzip file and you can copy the file straight out.
For those running XP, yes you'll need to install Winzip. Win 7 or Vista, you're all good.
I think the mistake Brett was you copied the Zip file straight to the USB and the Stern CPU cannot recognize the file. Double clicking the file on your computer then copying to the USB should fix it.
