okay, this leads me to my next big issue.  I was experiencing the same thing before I got the templates moved and all the rest installed, but I'd hoped it would go away.
So I've opened a template from you, and manually changed the ScoreManager Device setting to Kontakt 5.  Then loaded Snareline Lite manual into the player.   When i then enter a note on the staff using the mouse, it notates with Xs and whatnot, just as you'd expect.  This will not however playback upon entry or playing.  Now, if I use my USB keyboard to enter the notes, it will play back, but only notate on the line or space of the note I'm taping (C,D,E,F, etc.)
So I move on to the tenor voice.  Same thing as experienced above.  
Loaded vibraphone no problem.
