i have serch in the forum, but i don't have find any solution for my problem,
Some one can help me please? Thk in advance to all and sorry for my English

Not sure but it seems the issue might be a language issue. It appears your site is in another language. I am not sure but believe the images and sounds are all in English. Might check with the CB folks that wrote the plugin to see if it will work in other languages besides English.
