No camera found!

I am a complete noob to blender I want to make minecraft animations but I ran into a little bit of a ruff patch.
I know when blender is opened their is a cube and a camera, so I import my minecraft rig by pressing open>Then click on my rig and open it. The problem is when I open it their is no camera at all I tried alt H nothing happens, also in the bottom corner it said their was no camera found, what do I do? Please Help!

Add a camera (Shift+A)
Check you are not in local view (numpad /) or your camera is not on a non active hidden layer

Supply a link to your .blend file for review

I’m very new to blender I barely know what your saying I pressed shift+A but the camera cannot be clicked, like it’s grey while the other options are lite up. How do I check that my camera is a not a non active hidden layer?

Upload your .blend file to http://www.pasteall.org/blend/ and tell us the download link

layers are on 3d view header

Still don’t know how to do that anyways here: pasteall.org/blend/37717

On the 3dview header, change from Pose Mode to Object Mode, then add a camera with Shift+A
