Hope you got the calibration working?
One thing to watch out for that the help files don't warn you about is creating a Film and Scanner ICC profile and having both active at the same time. If you do this you screw up the colour management. Best to just set the ICC profile for film and leave the scanner profile as "Built in".
I have a free PDF download on my website describing the calbiration process in case it helps:
