I am trying to update a model from the 2002-2003 timeframe to the current 3.6 version. I think I'm about there, but when I run the preprocessor, it hangs up and there is nothing written to the PRE.OPT, PRE.WRN, and PRE.ERR files. I think my most recent snag is in the GRAPH.NPT file, if that helps.
Thanks,
Brian
