You can try to install a previous version of wordpress, if you visit the release archive http://wordpress.org/download/release-archive/ you can download the previous versions of WordPress. Also make sure you upload a copy of the older database that you have now. You always want to make sure you keep the original.

Thanks for the reply! Do I follow the update wordpress instructions
http://codex.wordpress.org/Updating_WordPress
to upload 3.0?
Those same rules would apply to when you are loading an older installation of WordPress. Also if you are using WordPress 3.0 hopefully you will update soon since most updates of WordPress have to do with security.
