TresCrows, if ThatGuy's explanation didn't solve your problem, ask Muhammad via e-mail to "support@tractorbynet.com" and you can bet it'll get straightened out.
I had doubts about downloading it when he said it was 230 pages, but I just let Windows 98 SE do its thing using the defaults. It downloaded in about 6 minutes to the "Downloads" file, double clicked on that, it unzipped to the "C:/temp" file, went to Windows Explorer to the "C:/temp" file, double clicked on that, and now my printer's hard at work. Of course, I do have WinZip and Adobe Acrobat Reader that was mentioned.
Definitely not my preferred method of buying a book, but it gets the job done, and quick.
