I am running Windows 10 on an HP Pavilion desktop. I'm happy to provide any additional details that might help.
Strangely enough, for unknown reasons, Musicbee's behavior has now changed dramatically. Musicbee now opens without error and I seem to be able to rip from CD properly. The "only" remaining problem I see: songs won't play. I click on a song and the tiny speaker icon appears next to it and the play arrow toggles to the pause button, but that's it - no sound and no incrementing/decrementing of play time / time remaining.
I hope I can get this straightened out. I've run Musicbee with no problems for a long time and dread having to learn a new organizer.
