Gromacs versions older than 3.1.4 allowed for more than one defaults 
section,
but then often the resulting parameter set would be different from what
the author had intended.

You should download the modified FF as suggested above.
If you do not have write permission in the top directory
you can put it in the same dir as your topology file.
