Quote - Since my question kinda got bumped off, no one actually asked for settings, so here are my settings for the current light set I was working on and my render settings, if there are other settings you need to see, let me know.

You should check your shadow camera settings; select the "Shadow Cam" for the light, to test if the object you are lighting is in the view of that camera (i find this easier to do when the light is a spotlight, not an infinite, so i set the type to spotlight before messing with the shadow camera, and set it back to infinite after i am done). Usually it is not that easy to destroy the shadow camera by accident, but still possible and often hard to track down.

Another thing i noticed in your screenshot, which might be relevant or not: the position of the brownish light in your light controls (the small planet with the moons) suggests that your brownish light is in a straight line behind the camera, so if you took a render with this configuration you will not see any shadow.
