I don't understand this statement.

This is where exact commands (in sequence) really help, or at least a stepwise 
procedure.  Are you adding a protein into a box that contains DCCP+water, or are 
you inserting the protein into DCCP, then adding water?

What is the exact error that grompp is giving you?  That the number of 
coordinates don't match? atom names don't match?
