Attempting to stack CR2 lights with flats, darks and dark flats. After the flats are analyzed and the normalization process starts this error box pops up - around 10 of them and it fails out.
Could be this is a bug that appears with very specific data, it's addressed in the next release which should be around the corner. Did you try to first make a masterflat, masterdark and masterbias? If not, does that also fail?
I was able to stack the flats as a separate process. I also used the dark flats as bias instead. I'm re-stacking the lights with these masters now to see how it all works.
