I reinstalled Reader X and then opened a slideshow made with PSA 2.0 and now the multimedia.api shows as being loaded. My slideshows sound wil not play. I saved the music files as mp3. Any suggestions. Thanks Robert
Legacy multimedia (sound and video not created using the Acrobat 9 or Acrobat X Flash-based tools) is potentially dangerous as it can be used to deploy malware. Legacy playback features are no longer trusted by default, so the plugin is not shown. If you open PDFs that contain legacy multimedia will see the yellow Document Message Bar promoting you for a change in trust settings, though we advise people not to do so unless they are totally confident in the authenticity of the PDF.
