I was using the old project files made with the cycles renderer and for some reason, the lights refuse to show up/work in texture or material view, causing everything to be black. It took me a good while to figure out what was wrong. Any tips on how to make these area lights work in blender internal would be appreciated as well. Thank you, and for others with the same problem, add a light and you'll see :)
