D800 - ColorChecker Passport - Dual Illuminant Profile

Anyone who has succesfully created a Dual Illuminant profile yet?

Yesterday I took two shots in a Light Box under Inca A and D65.

Converted RAW into DNG and load them into the ColorChecker Passport.

D65 first, which loads OK into the ColorChecker. Inca A later ... it says it's not a valid DNG file.

I swap their loading order and load the Inca A first, which loads alright. I then load the D65 and it says it's not a valid DNG file.

The files are full frame 12bit compressed.

I wonder if it is an issue of allocated memory within the ColorChecker Passport, since I have 16Gb RAM on my PC, running on Win7 x64 and i7 2600.

Any idea anyone? I wrote X-Rite. But, no answer back yet!?!?

Cheers
