When I rebooted and fired up Magic, there was no sound, as Magic had been set to Voicemeeter as its output. I am not sure if there was video activity when I played it. I could not find a way to set the sound output within Magic, so I used Sound Settings and Advanced to set it to go straight to the soundcard's input. I had to restart Magic to make that "stick". I had sound. But now when I play the project, none of the Modules is reacting to the sound: I just have a black video window.
Can anyone help me, please? This weird.

EDIT: This problem is also affecting other projects.
EDIT: I tried to install a later version and gave up on that. Reinstalling my older version solved this problem
