I recently reformatted my computer. I saved all of my music on an external hard drive, reinstalled windows, upgraded to windows 10 and then installed MC18 back on my computer. MC18 found all of the files but when I go to select ANY file the playback will not start or 1 second will play. No sound, no error message nothing. I tried installing MC21 and the same problem existed with that version as well. I searched the forum and found nothing similar to the issue I am having. Please help. Thanks. Ken
