  It is very hard to say what might be wrong with so little information. 
I have used CNS 0.9a to calculate structure factors and it worked fine.
Given that all columns are 0 suggests that your occupancy might be zero or
that CNS could not find any of your atoms in the structure file so you end
up with zero atoms in the s.f. calculation ...
  Hope this helps,
