When the Maddog came out I bought it. There was no VC. Then they came out with an addon for the VC. It was a separate add on, free for previous owners. Now I believe it comes with it, maybe. If you having problems it maybe a problem with where the gauge panels are kept in your FS folders. Panel cfg is not picking up the correct path. It happended to me. Make sure the aircraft.cfg , panels, is pointing to the correct path to find them.
Actually the best way, if now can help is their forum.
