2D surface mesh extracted from 3D tetra/prism mesh - Fluent error

I am trying to model the interaction between a thin fore sail and a thick wing sail in ICEM/Fluent.
I have been trying to mesh the thin sail in 2D but couldn't get a blayer to create quads around a single (open loop) curve. So instead I tried meshing in 3D (octree) with prism layers around the single curve which is set as an internal wall. When I delete the volume elements and surface elements I am not interested in and run a mesh check I get some uncovered faces and overhanging nodes, which are easily fixed, leaving no remaining errors/problems. However when I try reading the mesh into fluent it aborts with the following message:
Reading "C:\Users\Gerry\Dropbox\Sail\Mesh\3D_Mesh\fluent.m sh"...

Cell Centroid is (4.101032, 0.799421).
Clearing partially read grid.
Error: Build Grid: Aborted due to critical error.
Error Object: #f
The cell it refers to by Cell Centroid location appears to be a quad/prism on the upper surface of the wing sail/airfoil.
Does anyone know why I may be getting this error?
I have attached some images of my setup.
