I have a user that continues to get this error when she attempts to open any PDF files on SharePoint in excess of roughly 10MB. She has Adobe Reader XI installed as well as Internet Explorer 9. It matters not whether we use different versions of Adobe, or Browsers. So I am at a loss as to what to do here.
