Hi Jesse
The file seemed to playback just fine for me, including all the TenorLine shots.
I did notice, though, that the SnareLine Manual, TenorLine Manual and BassLine Manual instrument definitions each has had extra entries added to their mappings by Sibelius (
info on and the fix for this). I don't think that's causing the playback issue with the shots, but it could hamper note input when using a MIDI keyboard.
The only thing I can think of right now to help the shots is for you to make a screen cast recording of what you're seeing (or be as detailed in an explanation as to what that would show). All the way from just after Sibelius launch through playback of where the shots aren't playing correctly. Isolating that staff may help also.
