After I installed the update 7.2.11

I installed the recordbox Update today. I use my ASUS Zenbook Ultra 9 laptop with 132gigs of ram. My controller is the Pioneer FLX10 and i have never ever had amny issues with my gear. But after the update when i load a track in to my recordbox on my controiller is has a scratch and cracker sound. It also hangs and sound like it buffers. ITS TERRIBLE. When i unplug my contrller and play through my laptop soeakers it sounds perfect and doest buffer or crack at all. It has to be the update please please assist. I have a Gig this weekend And i need my gear to work
