"Adobe Acrobat is blocked" - Where to I accept the end user agreement which will enable me to access Pdf documents on the web?

I keep getting this message when trying to open documents from the web:

"Adobe Acrobat is blocked" - 

Where to I accept the end user agreement which will enable me to access Pdf documents on the web?

The Adobe website recommends this: (did not solve the problem)

Safari 7 and 6.1 block PDFs | Acrobat, Reader

Thanks for any help solving this annoying problem!

OSX 10.9.3

Safari 7.0.4

Acrobat Pro 11.0.0
