For Cross LE Win7 is the last supproted OS. Though it seems to work in 8.x
You could try installing the Cross Demo version AFTER you made a backup of your collection AND analyses folder as version 3.x may do upgrades to your collection.
If you install this you know if Cross 3.x sees the controller. Please be sure to use the 32bit version (so not thr one called 64bit).
Likely if the drivers aren't working for W10 it isn't possible to get Cross to work with it. Cross 'only' is the DJ program that uses the MIDI commands it gets and (if you have) the soundcard to send/receive sound.
