Can't change buffer size, control panel doesn't open

Hello, I can’t get rid of the crackling problem as I can not change buffer size due to the control panel in Cubase not opening. I head it was designed for a 32 bit system and doesn’t work on 64. Isn’t it time for it to be fixed?

Your audio system is where you change your buffer size. The button in cubase is supposed to open that but things go wrong in that chain of events sometimes.

Just open the control panel for your audio interface, should be a place to designate you buffer size.
