Again, what version of the engine are you running? Look under "Help" then "About" in WED.
For the "no light = black" part...change the Ambient color of the level under "File --> Map Properties --> Sun". For most outdoor levels you probably want to go with a dark purple or blue depending on how Yellow/Orange or White your Sun light is.
