3800 piezoDN negatives

I am again trying to print DN negs w the 3800. my negatives are too dark, even if i do lightening adjustment curves before printing. I have pro inks in the 3800, but I have been using the piezodn curve and not the pieazodn pro set. Should I trash these and redownload the 3800/3880 curves?
Any suggestions?

You need to use the curves for the 3880-PiezoDN-Pro because you are using Piezography Pro inks. The other curves are for the older legacy Piezography K7 inks.
