Error aerofoil
 

Hey,
I'm new to cfd and I am trying to mesh a basic 2D NACA 0012 aerofoil in ICEM 15.0.
I have tried following http://www.youtube.com/watch?v=EknKVAJGEJ8 but when I try importing into fluent 15.0.7 this error comes up:

Warning: Invalid face type 1. Skipping.

mesh
Error: Build_Grid: no cells in case file.
Clearing partially read grid.
Error: Build Grid: Aborted due to critical error.
Error: Build Grid: Aborted due to critical error.
Error Object: #f

I've tried redoing the mesh a number of times and can't seem to make it work. If anyone could give me advice on what I might be doing wrong that would be great.
Thanks :)
