I am sorry to hear about the problem reinstalling Music Collector. Please send me an email with your account information: name and email address on file. Or the old license key, that works too.
I found nothing even in the spam folder.
I did find a new version (23.1.1) but still will not let me register it.
Looks different from my last version.
