Check Boxes not being recognized.

I've imported a Word document with 300+ check boxes into Adobe Acrobat 8 Pro and none of the check boxes are recognized. I've run the Form Field Recognition feature from Acrobat and tried Livecycle to recognize fields yet every single time, it creates a text field around the check boxes and completely ignores them. In the original document, the check boxes are located inside a table. The text field that it places is around the border of the table. How do I get Acrobat or Livecycle to recognize the check boxes?
