[plugin: WP-PostRatings] Stars don’t show up ?

WP Post Ratings used to work perfect for me while using Revolutionary Theme, but now I changed to HeatMap Adsense theme and the stars don’t show up on posts – at all.

Do you know what might be causing this?

Also my second question is – can you make the stars and rating possible from the main page view… so basically you don’t have to click on the particular post and go inside it to rate the post but it can be visible from the main site and while you browse (older/newer posts) ?
