I receive the following error:

*** ERROR READING THE MO COEFFICIENTS AT   1  77
    THE INPUT VALUES WERE   2   1

Indeed,  1 77 does not exist :

1 75-2.45175653E-05 4.67451306E-07 8.18963875E-06-2.25179089E-05 1.05807521E-05
1 76 1.49291949E-05
2  1 7.09245510E-05 9.40896541E-06 5.16541291E-05-1.12328743E-04 1.24681158E-04

Do I need to pad with zeroes the $VEC section?
