Connie, what he's saying is that you can only run the ONE copy of 3Delight, regardless of how you got it. It's the license, and it's in the license agreement that you agree to when you install DS.  What's being confused is multi-processor and multi-core.  If you want to run it on separate processes, you have to buy another license, per the license agreement.  If you want to render using multiple cores, you just have to be running an OS capable of using as many as you have.
