I have this problem too. Space center work good, but if i start a flight - dead void around 500~ meters at any planet.
I was try to started game on version parallax 1.01 and 1.3.1 so, "dead void" anyway. I use recomendet version of kopernicus. KSP.log contains many and many of lines:
NullReferenceException: Object reference not set to an instance of an object Parallax.ParallaxInFlightOperations.Update () (at) ******************
