3D view not working! Help PLEASE!!

When I press F8 to view my terrain in 3D I am greeted with a message that says, (3D View) No Device Selected, or Device is not Build
I have tried building the terrain but still cannot view in 3D. What am I doing wrong?

Hi there,

have you made sure that you have a device selected either in the Device Workview (F5) or from the left-side device list, and that that device’s status is green or yellow?

The device status is green and I still cannot access 3D view. I also tried to do it manually through the layout view but it crashes the program when I enter layout view.

It sounds like there might be an OpenGL issue going on.

Can you see the small preview in the upper left hand corner of the leftside workbar?

Can you post the specs of your machine; also, have you tried updating your video drivers to the latest version? This often solves video issues.
