So, to avoid any confusion here is kind reminder to make sure you have Device Library (or both) on your USB drive. Device Library Plus (aka OneLibrary after recent update) is only for players like CDJ-3000/X, XDJ-AZ and above; CDJ-2000NXS2, XDJ-1000MK2 and below won’t read this libraries!
You can also use rekordox 6.8.2 which is stable and safe to use with older equipment
