DDJ-SR2 error message when connecting with PC-laptop (Win.8.1.)

 HI! 

Just updated from DDJSR to new DDJSR2 - and after connecting same old Asus PC-laptop I have used ok with DDJSR with USB.cable and when turning DDJ On - PC gives error message. Still DDJ opens otherwise normally and worked ok (Made 1st gig with it yesterdayevening). After gig, when closing DDJ it gave also error message "Cant connect audio" BUT still closed normally after that.

and yes I have updated the drivers beforehand...
