I, too, am not able to get either method to work. I would really like to see a chat I can enter with one click, like on another forum I belong to. WP chat hasn't worked for me in the year and a half I've been here.
Chatting is something I've suddenly come to enjoy a lot. I was afraid to do it for a long time, because it can be chaotic and unpredictable (like real conversation!), but I'm finally getting into my comfort zone with it. I feel like I'm building my skills for real life conversation, and I think a lot of WP members who've never tried it would benefit from the experience. It could be a real asset to this community if chat were more accessible.
