The tutorial is specifically written for version 4.0.5, but will be compatible 
with any version <4.5.  Since the re-organization of the force field 
directories, the information provided in the tutorial is not correct.

I would recommend not upgrading until the OP has sorted out the problem and can 
then (maybe) work out the appropriate translation to the version 4.5.x scheme.
