I would like to publicy thank Sue Evans and Simon R Galley and everyone at ILFORD HARMAN TECH LTD for having solved this problem.
It was my fault: I had not let the rolls to thaw long enough. Silmply as that.
I'd like also to stress to support ILFORD: they are absolutely THE BEST around. Folks that deserve every penny we spend on their products.
Absolutely first class support.
Thanks again ILFORD!!
