    Error message 'Acrobat failed to connect to a DDE server'

    lania53329610

      When I try and open a pdf file, I get this message. To read them, I need to open Acrobat 9 Pro and drag the file into that. Very annoying as I'd just like to be able to double click like I used to. Then it just stopped working. Any advice?
