If all that's OK, then we must focus on the most interesting bit you got in the output:

Weirdly, this seems to say that when your fopub script calls FOP (which Dan says happens at the end), its getting a command-line-parsing error, from parsing an unknown option; specifically,

Don't know what to do with -

That's one of those errors that's so weird you suspect it's not the real problem. Yet, it MIGHT be... but it would entail that somehow your fopub.bat file got corrupted--no?
