Hi NWChem Users and Developers!

I am trying to perform some test calculations using LiF as a test case. I try to calculate
the static polarizability and electric dipole moment at the MP2/cc-pVTZ and CCSD(T)/cc-pVTZ level
of theory, respectively, by requesting

property
 response 1 0.0
dipole
end

For DFT and HF calculations the code (v6.0 by the way) produces the desired output
but for MP2 and CCSD(T) following error occurs
number of frequencies:     1
frequency in a.u.: 0.0000000E+00
Perturbing field: electric
Using Dipole Length Gauge

 movecs_read_header: failed to open ./ IERR =                    21
------------------------------------------------------------------------
hnd_vec_read: failed to read header 911

Does someone have an idea what the problem might be?

Thanks in advance

Sven
