Recently active topics in AideRSS tagged with widget

I still can see the data on the aidrss site but nothing on my blog (http://www.optimainfinito.com). Tried to remove and reinstall the widget. Same result.
Checked the page with Firebug and found that the widget is returning a "502 Bad Gateway" message.

The scores for my posts are different on my website (using the aiderss widget) from the scores given to my posts in google reader. Why is that?

This is truly truly outstanding. Teffific work. I plan to spend a lot of time on it - Im looking forward to putting the widget up on our site and i wanted to know when I can do that? right now im receiving error messages. i have two site. www.coolwebmoms.com and www.volunteernewjersey.org

Thank you. Again, amazing job
