The way to fix the non-square table problem is (or at least was) to use the integer mode for CROSSTABS. E.g., if there are 5 possible ratings (1-5), and r1 and r2 are the two raters:

CROSSTABS VARIABLES=r1 (1,5) r2 (1,5) /TABLES=r1 by r2 / stat = kappa.

I don't have v19 yet, so cannot comment on what it is doing. What does your CROSSTABS syntax look like?
