I'm using both Superior Drummer 3 & SSD 5.5 (free) and when I try to mixdown or add to a Project once it runs the mixdown it throws the error 666 and I lose the audio. I have to restart Studio One. I've tried swapping over from one Drum program to the other bot they bot do it. My mix isn't clipping at all. I'm doing nothing different and i've been using both these programs for a while. It's only just started happening. I can't mixdown any of my songs and they need drums.
