a little tip:
replace the "simpleSpline" with "polySpline". add the start and end vector and afterwards a ";".
It must look like this:
polySpline 2 14
(0 0 0) (0 0 0);
blockMesh it. there will be an error. but it writes you the points out, that the polySpline would want to have. copy-paste them into blockMeshDict and replace the "polySpline" no with a "polyLine".
...maybe this is accurate enough for you.
I personally thin, there still is a bug in the polyLine. But till it is solved maybe you come along with my idea.

as I understood, there are some problems with simpleSpline in openFOAM 1.5 too.
with simpleSpline I got good shape, but the grid of cells is wrong. (i have also tried to change simpleGrading)
then I have made this trick with polySpline error and got a normal grid.
But for my algorithm use of this trick, that is based or error, is not the best way.
So I have a question to the people, who have more experience with openFOAM. Can I solve this problem with blockMesh, OF 1.6 or it's better to use some others pre-processors like Gmsh?

I have run into the same problem, and haven't gotten to far in the other threads either:
How to use the spline commands
Problem Meshing Airfoil
I am going to attempt to use gmsh. I was previously going to use netgen, but it cant regulate the cell size properly for cfd(good for FEA just not CFD).
