[Drupal] Error Message on Registration form

First let me apologize if this question is too basic or stupid. I am new to Drupal, new to CKeditor, and new to PHP, but I am hoping to learn.

I recently installed Drupal and CKeditor and put the Drupal registration form on the homepage. See: zobjob.com

The problem is that I see this error message:

Notice: Undefined property: stdClass::$data in ckeditor_user_customize() (line 41 of /home2/searchr1/public_html/zobjob/modules/ckeditor/includes/ckeditor.user.inc).

I found the ckeditor.user.inc file on my server, opened it, and line 41 seems very innocuous. It says:

    $data = $form['#user']->data;

Can someone tell me what is wrong and how I can fix it?

Thanks in advance!
