Have you activated the data file in
FOMM? What error exactly are you receiving in the console? I'm guessing that you've forgotten to adjust your formID for your load order - the first two digits of a formID should be the same as a data file's position in your load order. For example, 00 for Fallout3.esm, 0A for the 11th data file, 10 for the 17th etc.
