QTR-Quadtone RIP

I'm trying to make ICC profiles using QTR-Create-ICC for use with ABW on my 3800.

Using Spyder3Print to measure, all goes well using a 21 step wedge, so I tried the 21x4 
random patch file, hoping to build a better profile. I got the error message

<The Lab values are not in order. Cannot make a profile.>

Thinking I sent a bad format to QTR-Create-ICC, I tried the sample supplied with QTR, 
named QTR-21x4-random, and got the same error message!

I got the same results sending to QTR-Linearize-Data. And with the QTR-51-random 
sample file.

What am I doing wrong that I can't even get the sample files to work?
