Cant start MaestroControlCenter on Raspbian

Hi. I’ve installed the MaestroControlCenter app on a raspberry pi running Raspbian but when I attempt to start it (via VNC) I get the following:

pi@raspberrypi ~/maestro_linux $ ./MaestroControlCenter

Unhandled Exception: System.TypeInitializationException: An exception was thrown by the type initializer for System.Windows.Forms.XplatUI ---> System.Net.Sockets.SocketException: The requested address is not valid in this context

I can run ./UscCmd ok from the shell. Will MaestroControlCenter work over VNC?

Thanks

It seems the library doesn’t find the X11 display.
What is your DISPLAY environment variable set to?
Does your VNC server implement that X display?
