Problem with my Denon MC6000MK2 conneting to VDJ

I have a gig tomorrow and all of a sudden my system is coming up with an Asio not being created in Denon dj buffer Please help

Has anything changed on the lappy ? Eg: other software loaded? Operating system upgraded? Other audio software upgraded? Other midi equipment or soundcards connected briefly recently. Eg: tried a friends controller on my lappy?

PC ? MAC what is your system Spec :slight_smile:?
