WordPress.com Stat not working

after I updated my sites to the new version of wordpress the plugin “wordpress.com stats Version 1.8.1 | By Automatti” Stopped working on my sites: http://www.sondrahicks.com and http://www.themissfitzsite.com

I really need a fix to this cause it helps me keep track of the flow of traffic and what countries I am more appealing to.

Thank you
