You might only see a blank page, and not the pdf file, due to a problem with the integration of your Acrobat and browser.
There are three ways to solve this problem:

1. Save the pdf file:

• Hold your mouse over the link to the pdf file
• Right click
• Choose "Save Target As" in the pop-up menu
• In the "Save As" dialog box, select a location on your hard drive, and then click "Save"
• Start Acrobat Reader
• Open the file you have just saved.

• Exit Internet Explorer (or other browser)
• Start Acrobat or Acrobat Reader
• Choose "Edit > Preferences > General > Options" (Acrobat 5.0 or Acrobat Reader 5.0) or choose "File > Preferences > General" (Acrobat 4.x or Acrobat Reader 4.x)
• Deselect "Display PDF in Browser" (Acrobat 5.0 or Acrobat Reader 5.0) or deselect "Web Browser Integration" (Acrobat 4.x or Acrobat Reader 4.x)
• Click "OK," and then exit from Acrobat or Acrobat Reader
• Restart Internet Explorer (or other browser).
