QTR-Quadtone RIP

When I drop the following file onto QTR-Linearize-Data it tells me:
The Lab values are not in order.
Cannot be linearized.
Yet that are in sequence in the input file. I am not shure how to make this work. 
I am trying to make a profile for digital negatives for carbon prints, measured using an i1 and ColorPort using Scott Martins article at http://www.on-sight.com/2012/02/22/using-colorport-for-qtr-grayscale-and-alt-process-measurement-and-profiling/
Paper base is a little more off white than usual beacuse I am fine tuning stuff with reject pearlescent hand sized paper and just trying to make the process work before printing a final wedge.

Thanks
David
