Oh, in their infinite wisdom, Denon DJ decided to change the database with the release of Engine OS/Engine DJ 4.1. This new database is not back-worth compatible with earlier versions of Engine DJ/OS. As a result, the Denon Conversion Utility (DeCU), Denon eXtractor Tool (DeXT) and DJ Conversion Utility Streaming (DJCU/s) are no longer compatible with any version 4.1 or higher.
If you're using an earlier version, you're in luck—it still works just fine. You can always downgrade, but don’t forget to restore an older collection database if you've already updated to Engine DJ/OS 4.1.
As for what exactly changed and whether it's fixable... well, I haven’t had the pleasure of digging into that yet, so no promises! But it is first on my list after Amsterdam Dance Event.
