Does Not Load….Loading

Hi there…i am running the latest wordpress with quickcount. Installation went well, but when i click on quickcount within admin panel, nothing loads except the words “Loading” and the same is seen at the widget area. (http://www.unitedfreeworld.com)

Just for your info and if it is useful: i do not use default WP_ table prefix, i have changed them for security reasons.

All help and suggestion appreciated

cheers
