[Plugin: WP Carousel] No options appear on Carousel options pages

Hi, after installing this plugin no options appear on Carousel options pages. Using IE to display the Carousel 0 options page I get this error:

Messaggio: ‘window.document.forms.post_wordpress.type_list’ è nullo o non è un oggetto
Linea: 12
Carattere: 2
Codice: 0
URI: http://www.nokioteca.net/blog/wp-content/plugins/wp-carousel/js/edit.carousel.dropdown.hide.divs.js.js?ver=3.0.4

Is there a conflict with an other plugin? Which one?? Please help me..

Thanks a lot in advance 🙂
