Vault from "From Features"

Hey, I am tryin to create a masonry vault and use RhinoVault 2 to do it. I have this initial from, which is below and I wanted to make the patter. I have tried all the patterns from lines to triangulation and they all work except “from features”, which is what i need for my geometry. It was working before, but isn’t now and keeps giving me this error message. Is there anything I could have done wrong because it was working before, but all of a sudden just wont anymore.
