I can download a PDF file from the web site. Whats wrong?
The trouble could be in any one of several places. Our server could be busy or, depending on how you connect to the Internet, your ISP could have a large amount of network traffic to handle. It is also possible that part of the Internet has failed. Typically, these problems are temporary. Please try to download the PDF file you want at a different time. If the problem persists, please contact the chapter webmaster.
