Working with the most recent version (4.0.5) is always recommended. The only reason to use an old version would be for consistency with older work. Can you post your [ pairs ] section so we can have a look? What type of machine are you using? If it's Windows, then there may be problems with the file if it was edited using anything other than a plain text editor, in which case dos2unix is your friend.

    This may be some new error-checking mechanism introduced in version
    4.0.  In your topology, a function type for pairs should be defined,
    according to the header of this section (from pdb2gmx):

    [ pairs ]
; ai aj funct c0 c1 c2 c3

    If your "funct" column is blank or says "0" then that could be
    giving the error.

               what does this pair type mean and how can i solve it??
        plz help me


           The error message is pretty clear.  Somewhere within the
        topology,
           you have a "0" in the "type" column, which doesn't correspond
        to any
           known pair type.
