Your project is private so only you can see it. You have provided no screenshots. That is not helpful. The Copper Area defaults to being assigned to the GND net so the possibilities are: 1. You have no GND net in your PCB;  2. You have placed the Copper Area so that it covers an area of the PCB that does not include any object on the same side of the PCB that is assigned to the GND net; 3. You have changed the net name for the Copper Area to something that does not exist on the same side of the PCB in the area of the PCB that the Copper Area covers;  4. You have placed the copper area outside - or you have no - Board Outline;  5. You have set the copper area to be Invisible in the right hand Canvas panel;  6. You have made the layer on which you have placed the Copper Area invisible in the Layers floating palette.

@andyfierman      Thanks a lot for your reply. I will check all these tings out you mentioned and see if that will solve my problem.... Thanks again.

@Ovemand Hello andyfierman.... Thank you for your help... that solved my problem. My GND net was not assigned correctly. I changes that and everything works fine now...SUPER.
