I'm working with an editor who uses Wordfast Pro and I'm a bit at a loss as to what to do with the .txml file I got from her. The workflow is: .sdlppx from a client, .sdlxliff from me to the editor, .sdlxliff.txml from the editor back to me and then I have no idea how to proceed to get to the final signed off .sdlrpx. I have installed the Wordfast file app from the app store and it does show in my file type definitions.
