Contact Form 7 messes my built-in widget

I use WP 3.2.0 and the Contact Form 7 plug in messes the built-in widgets up. (I already diactivated all the plugins to see which one was causing this issue)

A Widget called “RokNewsRotators” stop rotating and the texts (posts excerpts) doesn’t show up any longer.

Is there any fix for this?

Thanks!
