How do I add a new forcefield (.off file) to Material Studio v6 Forcite?

I have a .off, .frc and .dat file for a Forcefield and would like to add it to Material Studio v6, Forcite Forcefield Manager.

How do I do this? I have copied the files to 'C:\\Program Files (x86)\\Accelrys\\Materials Studio 6.1 x64 Server\\share\\Discover\\res' however they still do not show up in the Forcite Forcefield Manager?

Kind Regards,
