Pioneer CDJ 3000 HID mode problem

Over the weekend at a gig, I connected my Mac to a pair of CDJ 3000s via the Pioneer Aggregator and selected Decks A+B, as per normal. I rarely had any issues in the past with Pioneer’s HID mode, however this time I faced the following:

• Mapping - The mapping was all messed up. For example when I pressed play on Deck A it started playing the track in Deck B. Also when I pressed the CUE button on Deck B, it stopped the track on Deck A, etc. Weirdly though, the CUE hot points on each deck (1-8) were working fine. Thankfully I had my X1 so I could exercise some control.
• Sound quality - After 20 - 30 minutes of perfect sound quality, the sound coming out of Deck B became massively distorted. That was the trigger for me to switch to my USBs.

Does anyone know how to solve this issue? Is there a way to restore factory mappings for CDJ 3000s? Although I doubt these were altered in the first place.

One thing that may be linked to this is that a couple of weeks ago I downloaded a mappingfor the Pioneer Opus. I'm not sure if this could have messed up the CDJ 3000 mapping altogether.

The sound distortion was also quite worrying, as I don't think it was linked to the mapping issue.

Any help would be greatly appreciated.

Thanks!
