    So clearly you have broken the file format, probably of at least
    atomtypes.atp. However we can't guess how if we can't see your
    changes (e.g. use the diff tool).<br>
    <br>
    Also, you need to answer the last question Justin asked, because
    that answer is likely to reveal your problem...<br>
