Issue with FLX4 Driver

Hi there, i got a new DDJ-FLX4 and it was working alright until yesterday I noticed that the selection knob was not changing the cursor in serato lite (controller is 4 days old). I then checked Windows device manager and saw that there is no driver assigned to the controller. Can someone please provide the driver for the controller, or let me know where it is installed so I can reassign it?
