PY NR's may have a couple of causes.

For NR, @PhoebeRoberts has pointed out the key solutions.  The main thing is really in your input of state source and also the blank, N S thing.   So far I have not encountered any software problem.  I do about 20 - 30 CA-NR every year.

If you feel you've checked it all, one suggestion is to email Lacerte with the file and ask for the details.  This year I did it five times.  Two showed Lacert Gremlins.  Three showed user (i.e. yours sincerely) problem.  The turn around time was within 24 hours.  I have no problem with Lacerte support this year, but then, I only threw them clear, focused problems. 

Good Luck!
