Reply to Numark DJ iO issues with traktor

I've been using DJ iO with Traktor Pro with no issues for the longest time. Recently, I repartitioned by drive and reinstalled Traktor Pro and the drivers for DJ iO. The problem now, is that Outputs 1 & 2 both only play out of output 1. So, both decks play on one deck. I've reinstalled both several times and tried all sorts of options in audio setup and other settings. I haven't got the slightest clue what the issue is.
