File not found error in deejaysystem

Hi. I currently use Deejaysystem and have had no issues with the codecs until recently. File not found error. It plays perfectly well in VLC and windows media player.
Any ideas?

I use version 17.2.5. updated and same error. Went back to 17.2.5 and error persists but only on video mixes. plays 3 minute files ok but not hour long videos. File not found.

That error does not sound like it is codec related.

I have put it on blu-ray and it plays fine. I will sort the issue, so no worries.

If you are using an external drive that is shared between systems, then it probably is a problem with the file access permissions.

You can fix that with takeown.exe from WIndows:
