I was told that Sibelius 7.5 is not compatible with Kontakt 6 so I added Kontakt 5 vst to use Virtual Drumline sounds. After installing Kontakt, now my Sibelius 7 Sounds are not working properly. Seems that many sounds (mostly brasses) are not loading on start up and when I "test" my audio engine in configuration I get no playback. See pics.
Thanks!
