I just noticed the Get Cross Demo on top of the page points to a webpage with the Free products.
COuld you try if this link works for you
[PC] Cross DemoThis points to the Cross Demo.
As far as I know you have all Cross functions including HID and MIDI.
If you setup the CDJ's it should work without a problem (please first try the default HID mode). You could set it to MIDI mode in case you want the CDJ to behave different.
