It looks to me like you are trying to start dynamics from your original
unminimized complex_ionized.pdb coordinates.

Since from your previous email you have binaryOutput no you need to
replace ../common/complex_ionized.pdb with ../common/complex_eq.coor.
Otherwise you would use binCoordinates as you have commented out.
