I'm new to Blender. I've got a scene, I downloaded from an Internet forum about a year ago, but light isn't working.
If I create a new file, add a mesh and shine a light on it I get light.
When I follow the same process in the scene I want to light the spotlight has no effect.
Thanks to @Timaroberts it appears the scene is upside down or something.
When I move the lamp underneath the plane and rotate it the scene lights as expected.
