I used Winzip 8.1 to create the archive on a Win2K machine. I just downloaded the files again from the above link and it worked fine. Possibly you are using an older version of Winzip. You might also try copying the files to 3 floppies and see if you can get extracted that way. If you continue to have problems let me know and I'll create the files with another archive utility. What is your preferrence? Keep in mind the PDF is about 1.2 meg and there is 500K filesize limit on uploaded files to the board, so whatever archive utility I use must support splitting the file.
