Help with the ELGGBOOK theme and the CAPTCHA function

I am new to all this elgg. I have installed elgg on a server at home and was able to install it and get it up and running just fine to include using the captcha function. However I then installed the elggbook theme and now when a user attempts to register they get a message indicating that the text entered does not match the text on screen. I noticed that the theme does not show the captcha widget on the screen and I think this is what is causing the problem. Does anyone know if there is a fix for this?
