Kens has decent instructions for getting Couch Potato TV and the IPTV Simple client working in tandem. The only thing I'll add is if IPTV Simple client doesn't load, click the m3u server START button on the IPTV Simple client dialogue inside Couch Potato TV.
Work through the directions slowly and you will get things working. Guide selection and activation is available from the IPTV Simple client dialogue as well.
