Strange shadow problem- help please

[Metallimonkey]

Hey Everyone,
I'm having some shadow problems and if anyone knows what the solution might be, let me know ... Thanks

I'm using the Basic version

[J_Bug]

Looks like light leak. Are all of the edges there welded or else closed geometry placed on each other? Can you render with "Show Samples" and post it?

I would tick "smooth surface shadows" in the rollout of your light and give that a try.
