Hi, new to the forum but not to the mcx - it has never been 100% reliable but for some reason seems to be getting worse recently. I have tried to open a support ticket but received no response 
the screen freezes and in fact all buttons stop reacting but still work to some degree for a while.
I have tried multiple laptops (windows) and I am on the latest version of serato and firmware on the mcx8000.
Yesterday I was DJing at a party and on the right hand deck selecting a new track with jog wheel (using serato not usb) and it set the track on the left hand deck which was live playing a track, is this something I have pressed or an issue with the deck? Obviously this was quite embarrassing for me but all was forgiven by the end of the night …
Any help would be appreciated!
