Unable to Download a PDF

I cannot download a PDF and open it from the internet--not with Adobe Acrobat Pro X nor Adobe Reader even when the file is from Adobe.  I don't get it.  I am using iMac with Mountain Lion OS (10.8.2).   I reviewed the Preferences but I don't see any topic related to this.  I'm ready to download a file from Adobe and cannot.  If I close the window I don't know if I will have a second opportunity for the download Market Intelligence Report: "Enterprise Social Media Management Software". I have block popups checked with the exception of www.adobe.com and success.adobe.com (but even unchecking that does not make a difference).
