I used "Live Helper" on my 3.1.0 version and all worked well but I did have a few strange things happening at the checkout so I have removed it for now and I will try again when I am up and running on 3.2.1
I added my code in the powered.tpl so the "Live Helper" logo displayed below the Powered By image. I don't think it was that that cause my problems so you could try it there and see how yours work. One tip is to code it as your secure address to allow it to sail through when your customer checks out.
