Frequently Asked Questions


My Refcard Won't Download. What happened?

While most users won't have any problems (thousands have successfully gotten their PDFs), there are a few users that might experience problems.  The primary places where this might happen:

  1. You have an overly aggressive firewall on your network
  2. You're using an older Lotus Notes + IE 6 to read your email and download the PDF
  3. You're using IE7 with IE7Pro
If you have problems downloading, DO NOT TRY TO DOWNLOAD MORE THAN 5 TIMES.

To solve these problems, try the following things.  If you're already hit your maximum number of download attempts, please email support@dzone.com and forward us the email that contained your download link.

  1. This sometimes happens with IE 6 and the Firewall.  Try using IE 7 or Firefox.
  2. We've had reports that just using IE 6 works fine, Lotus Notes appears to be the problem. 
  3. This is a recent report, but it looks like IE7 Pro causes some problems with downloads.  Check that other downloads work or try Firefox.
