arracing - That should have worked... Any polls that have been closed have a value of 0, and any that are open have a value of 1. You could try changing that to poll.active!=0. It should work either way, but maybe that will help. If not let me know, and also do me a favor and post exactly what you have for that query so I can test it out if that doesn't work.
ElenaBB - You didn't follow the instructions in the readme file.
Next find the Styles section near the bottom left frame in your Admin CP. Click on "Modify" under Styles, then click on the [fonts/colors/etc] link. Near the bottom of this page you will see a section for Image Paths. Set the "Image folder path" and the "Title image path" to the full URL for your images folder inside your forums (ex - /forum/images or http://yoursite.com/forum/images). You must do this for each of your styles, otherwise your images will not show up.
