WP Error messages about depracated widget functions.

I am getting error messages on my Wordpress Site. www.calicoridgeband.com My server support person says that an upgrade of Catchbox might solve the problem but he was not confident. The error messages are visible by going to the web site. Is there an new version of Catchbox that will solve the problems shown in the error messages? Is there a way to just defeat the error message so they won't show up on my web site? Thanks. Vic
