"can't find knoppix filesystem, sorry." when booting from disk

It may be that you have only copied the CD image,
and have not expanded this image into its several components as a LiveCD.

Alright. I am currently downloading the following:

KNOPPIX_V6.4.4CD-2011-01-30-EN.iso
KNOPPIX_V6.4.4CD-2011-01-30-EN.iso.md5
KNOPPIX_V6.4.4CD-2011-01-30-EN.iso.md5.asc
KNOPPIX_V6.4.4CD-2011-01-30-EN.iso.sha1
KNOPPIX_V6.4.4CD-2011-01-30-EN.iso.sha1.asc

It doesn't appear that my sub-par connection at work will have this accomplished before I leave so I will be in early tomorrow to try to create the CD again. Does this look like the correct full set of files that I should have for this attempt?

Thanks,

Ian
