John, there is no secret from my end. I just downloaded the file in that DJVU (?) format. When I tried to open it my Mac automatically asked if I wanted to instal DJVU viewer. I clicked yes, it installed and now I can read the files.
If you are having problems with this, I can help you. The program converts the files into PDF. If there is a specific file you need, let me know. I will download it, convert it and email it back to you.

Thanks,

Ted
