Second problem first: VDL does not work with the Aria player. So the fact that you can't load VDL instruments into that player is expected. As far as why Kontakt Player 5 is not appearing as a device in Score Manager is difficult to answer. It would be helpful to know what OS you are using, Windows 7/8, Mac 10.

Let us know your computer specs and I can get back to you with better information.
