Corona renders Black images after updating to v5

[Bobbysmith05]

I've recently updated to version 5 only to find I can't render anything only black screen when through a camera and occasionally if I render through viewport I sometimes get off items rendered but the rest of the scene is black? Any ideas?

Max or C4D? Which OS? What was the previous version of Corona you were using? Example image from the scene (back when it used to work in whatever version it was, vs. what you are getting in 5). Perhaps send the scene in. Is it all scenes, or just some? What about a new scene with just a cube and sun / sky?
