Some users are having trouble with Adobe Acrobat or the Acrobat Reader displaying PDF files. We recommend not using Adobe products as "plug-ins" to your browser: to disable this feature, close your browser and open Acrobat (or Acrobat Reader). In the preferences, you need to deselect "Display PDF in Browser" or "Web Browser Integration" (or some similar choice). Then revisit our page and try again.
