User Content Previews Not working

Hello,

I'm working on a few user-presets for my MKII. I want to add previews for my presets. But I can't hear the sound of the .ogg file in Komplete Kontrol.

What I did:

• Created a preset file name TEST and saved it. File can be found in C:\Users\*\Documents\Native Instruments\User Content\Test\TEST.nksf
• Created a sound file and saved it as .ogg. File can be found in C:\Users\*\Documents\Native Instruments\User Content\Test\.previews\TEST.ogg
• Updated DB of KK

Where is the mistake ? Hope someone can help.

Best Regards, Marcel
