virtual cockpit

I have FSX, downloaded from Simviation a C90 plane, file kaf90_v3.zip, for FS 2004. Plane is there, flying beautifully, but no virtual cockpit. I got panel from Beech 58, replace C90 panel file, but can't see VC. In fact, others panel also don't show VC when replacing C90's.
Is there some editing to be made in cfg file, for instance??
