Just by uploading the vars_wordlets files will not be enough. Have you changed the other realted files too. I think you will get a full description below the text of the Sticky Hack (I know it was in the 6.1 version) on what other files to modify to make the vars_wordlets file work.(This is in the section of the text, at the end, where it describes what you should do if you dont have the file already up in your board)
