I wrote the tutorial you are following. It is for GROMACS 3.3/3.3.1.
If I remember correctly, sc-power is an option that is new to GROMACS
3.3, hence the tutorial will not work in 3.2.1. It is likely that the
"blowing up" you are experiencing is due to using soft core parameters
which are inappropriate.

Maik was referring to the time-dependent scheme for changing lambda,
which I don't particularly recommend.
