If you're using the restored content mod and/or M4-78 then the game files get altered so the trainer shouldn't work. However, you can still use the savegame editor for items, abilities, force powers, stats, feats etc. I use it myself, so I know it works fine.
It's linked in the miscellaneous section and when you run it the editor may require you to manually locate the TSL directory if you are using the steam version.
That would be awesome!
