Comment Spam Pack plugin conflict


I followed this guide on security and installed the bullet proof security plugin

The problem is that when it is activated it causes a conflict with the comment spam pack wpmu plugin – what happens is that the captcha image that is supposed to be displayed in the comment form is blocked so it does not display the image needed to enter…

When I disable the security plugin the comment captcha is displayed… does anyone know how to fix this??

Thank you,
