I just bought and installed the latest version (update) of video pro x but the command
  "Activate content pack (s)" in the "Help" interface does not appear. How can I activate HitFilm 360 Pack? also in the "Effects" interface the "Additional effects" command does not appear. Magix's original message: You can activate your HitFilm 360 Pack directly via the Video Pro X interface under "Help"> "Activate content pack (s)". You may need to update your program version first. Your HitFilm 360 Pack will be activated and ready to download via "Effects"> "Additional effects".
