Rendering Sequence comes out black

Oh that worked little bit, it isn’t completely black anymore but the scene in the render is much much darker then the actual scene. Some parts are barely visible now. Does that have to do with the fact that when I press the “Play this Level In a New Window” button up top, all the lights seem to disappear from the World Outliner? I don’t know how to fix that either, I tried everything I know. ;=; Thanks a lot for the help so far, just this last issue left. ):
