CDJ-850 detected on rekordbox 6 but does not select decks

Hi,

I am on the free trial of the core plan I purchased on rekordbox 6. When I connect my CDJ 850s to my laptop in PC mode, it displays connected but when I open rekordbox it does not allow me to select decks for them. The decks are running on v1.13 and the core plan is activated on my rekordbox page. They are also connected to my laptop and not through a USB hub. Any idea what's going on? Otherwise I'll have to cancel the sub.
