That´s what I hope, too. I´ll have a closer look today.
Moreover I conceived the following idea: Two weeks ago I made a complete backup. Might it have happened that some audio drums had been moved instead of only being copied? I think that could be a reasonable explanation, couldn´t it? And wouldn´t a solution be easy then - I´d just have to copy the audio drum folder from my computer onto the Audya´s drive. What do you think?
