Twitter counter not working

Hello,
I have recently downloaded WP Social Bookmarking Light. It works like a charm, but the twitter counter is not working correctly. I had about 8 retweets this am and the counter stayed at 0. Currently it is upto 4, but still underestimating the social impact. The site is rebelem.com Any thoughts on how to fix this?
