Hi Silvio,

This should work. Here's a small closed shell example that works:
echo
start water
geometry "system" units angstroms nocenter noautoz noautosym
O     0.00000000    -0.00001441    -0.34824012
H -0.00000000 0.76001092 -0.93285191
H 0.00000000 -0.75999650 -0.93290797
end
set geometry "system"
basis
 * library 6-31G
end
occup
6 0
2.0
2.0
2.0

1.0

end
dft
xc b3lyp
vectors output occup1.mos
end
task dft
dft
xc b3lyp
vectors input occup1.mos
noscf
end
task dft
unset rt_tddft:*
rt_tddft
 load vectors occup1.mos
tmax 200.0
dt 0.2
nrestarts 0
tag "kickx"
print dipole
field "kick"
type delta
polarization x
max 0.001
end
excite "system" with "kick"
end
task dft rt_tddft


Here's an occup example for an open shell:

occup

1 1
1 1
1 1
1 1
1 0
0 1
end
