Error in run.emproc of megan2.1

MEGAN

Hi everyone!
I’m using MEGAN2.1 to calculate biogenic emissions and got errors on the last day of each year (December 31st). Does anyone know what might be causing this?
Here is the log:

It looks like line 81 is the WRITE statement below.

  IF( GDAY == 0 ) THEN
      FERTLZ_ADJ = 0.
  ELSE IF( GDAY >= 1 .AND. GDAY < 30 ) THEN
      ! first month of growing season
      FERTLZ_ADJ = 1.
  ELSE IF( GDAY >= 30 .AND. GDAY <= 366) THEN
      ! later month of growing season
      FERTLZ_ADJ = 1. + 30. / FLOAT(GLEN) - FLOAT(GDAY) / FLOAT(GLEN)
  ELSE
      WRITE( MESG,94010 ) 'Invalid date specified; date = ', 
 &                        DATE, 'growing season day = ',
 &                        GDAY
      CALL M3EXIT( 'FERTLZ_ADJ', 0, 0, MESG, 2 )
  ENDIF

Perhaps others can solve this issue with this additional information.
