Command not Found error when running Jigdo-lite to download isos

["Frances A. Brown" <annieb42@bellsouth.net>]

Hello,

I have been trying to use jigdo-lite to download the iso images (I'm using
Windows XP home ed), but when I enter the url at the first prompt with a
return I get the following error message:

jigdo-lite: sed: command not found

the url I am using is the following:
http://non-us.cdimage.debian.org/jigdo-area/3.0_r2/jigdo/i386/woody-i386-{1_
NONUS,2,3,4,5,6,7}.jigdo

I have tried the us site, have tried specifying only one file at a time, all
with the same result: command not found.

Any ideas on how to preceed?  Help would be appreciated.

Regards,
Annie
