[ccp4bb]: Indexing I222?

This is not the same problem as discussed here a few days ago!!
Denzo proposed the highest symmetry lattice as I centered orthorhombic
with the skew parameter 0.18 %. This gives space groups I222 or I212121.
The predictions in I222 never meet the spots. The unit cell parameters
match almost exactly those of a similar structure of the same protein in the
same space group. So it looks likely. But the misfit is BIIIIIG  (30 degrees
in orientation of reciprocal space rows or more, different pattern, even the
spacing a bit bigger).
Anyone has any ideas what to do?
(Except indexing in P1, which is possible and searching for symmetry)
