        Tim,

        What is your USEREDFILES (use reduction files)
        parameter?  By default it is NO, I believe you want it
        to be YES.  If NO it basically calculates on the fly,
        vs YES where it stores the calculation.

                        USEREDFILES  = YES

        Also read the help docs for more info on the
        parameter.

        chris.
