I would if I knew R.
I figured out a work around. I modified the PSM routine so that it only
output the treatment and matched control records (<20,000) to the new
dataset and that worked. If I tried to output the unmatched records also,
it crashed every time.

Have you tried running PSM in R directly (i.e., without going through SPSS)?
