Ron Reeder QTR profile for 3800

Bonjour!

First of all, excuse me for my english, I'll try to make my problem as understandable as possible..
I try to create a profile for my Epson 3800 using the method of Ron Reeder found on the pdf "qtrmanualsv3."
I want to make digital negatives for palladium prints.
So i step the explanation for the creation of the profile, but when I use "install3800.cmd" to install it, it always returns me the same error:

"Creating curve UCmk-palla-101212
Qlimit did not return a valid curve at / Library / Printers / QTR / bin / quadprofile line 214 "


I copy here the contents of "UCmk-palla-101212.txt" :

# QuadToneRIP curve descriptor file
#
# K3 ultrachrome inks for

PRINTER = Quad3800

CALIBRATION = NO

GRAPH_CURVE = YES

N_OF_INKS = 8
DEFAULT_INK_LIMIT = 100

LIMIT_K = 18
BOOST_K = 25
LIMIT_C = 18
LIMIT_M = 18
LIMIT_Y = 18
LIMIT_LC = 30
LIMIT_LM = 30
LIMIT_LK = 35
LIMIT_LLK = 0


N_OF_GRAY_PARTS = 2

GRAY_INK_1 = K
GRAY_VAL_1 = 100

GRAY_INK_2 = LK
GRAY_VAL_2 = 33

GRAY_HIGHLIGHT = 0
GRAY_SHADOW = 0

GRAY_GAMMA = 1
GRAY_CURVE =

COPY_CURVE_C = K
COPY_CURVE_M = K
COPY_CURVE_Y = K
COPY_CURVE_LC = LK
COPY_CURVE_LM = LK


If any of you know what is wrong with my approach would be very helpful!!
Thank you in advance!

after Gray_Curve= you have to put a dummy curve like "0;0 100;100"
