help me on reading this grib file in GrADS

[dongdong]

  Hello everyone:
      I would like to calculate vertically integrated moisture flux. But i can't read the wind file in GrADS.
      I use grib2ctl  forming the control file.  when GRIBMAP the control file, it crashes after the following message:
        ....
        ....
  6 btim: 1957120100:00 tau:      0 dtim: 1957120100:00

GRIB file format error
rc = 53

      Although every records are matched,the "GRIB file format error" cause no index file. so i can't read U and V in GrADS.
      The wind file,e4moda.pl.dssuv.1957, and grib2ctl.beta are attached. Thank you very much for your caring, any help will be greatly appreciated.
