So far I red the "PlogueEngine.dll/bundle cannot be found or initialized" Error - which cause that no sibelius playback is workin (MIDI Wavetable is still running) - so far I red about it, it is an iTunes - a MacOS - Problem.
But I'm on Windows 10 and get this Message.
In the "Play/AudioEningeOptions/"-Window my sounddevice is showing up in the "available" part with grey textcolor. Its inactive and cannot be clicked.
There is a PlogueEngine.dll in my System folder... maybe this is broken data and I could try to replace it with a working .dll?
The System was working fine. The error occured suddenly.
Sibelius 7.3.1.
Windows 10
M Audio Adiophile (is still working fine)
