I'd have to have a look to be honest. Mine was a bitch to get working. Mine works by either clicking on View Document or double clicking on it in the list. It should open up Acrobat. Download the latest version of Java Runtime and apple quicktime, apple have integrated quicktime into their stupid itunes application now :( so youll have to use that. Install latest version of acrobat and try again.... Thats all i did. Make sure you uninstall all the old versions of acrobat, quicktime and java run time.
