Camera View, Cannot access

Hi,
I have just installed Blender 2.42a, the problem is I cannot get the camera view to work, whether I select it through the menu view/camera, or by hitting the numpad0 key, it just doesn’t change, I can cycle through the top,side and front views via bith methods, but can’t get the camera view.

Hope someone can help, thanks.

Nevermind, I have it sorted, I am an idiot :eek:
