[Plugin: TweetMeme Button] Where did the botton in the feed GO?

I dont see a support forum on their site or I would have asked this question there. Previously with the wordpress plugin that allows for the tweetmeme button, it used to show up within feeds, and there is a setting to do so. Unfortunately, the button no longer appears within the feed even with this box checked. How can I get it to work again within the feed as originally it was working just fine?
