according to your result, everything's clear:
the job is concluded, but nothing had actually run: take a look at the warnings in your DEMO.TXT, all the tokens related to RF sims are crossed-out or "unreconisable" as the polite output file shows below. I run the same gpsvco.sp with hspice.exe (NOT hspicerf.exe), and it gives exactly the same result. I guess you have probably mistaken hspice.exe as hspicerf.exe ....
==> attached below is part of your DEMO.TXT <==
