You've followed the correct procedure. If the new residue is a ligand of
sort, it may just be easier to create an .itp file for it (using one of the
user-contributed programs, or something like PRODRG).
If you still want to use the .rtp approach, provide more details, like the
actual .rtp entry and the exact error message that you're getting from
