hey wallee,
first of all thank you for trying visualCaptcha for wordpress and Thank you for you contact.
From previous experiences, I can tell you with 95% certainty that the problem is with the custom template that you are using on your site. 🙂
By default BuddyPress overwrites the default wordpress templates, and by doing so, it will brake every plugin that uses or rely on the wordpress standard hooks/positions/templates.
Please check this link:

If you need further assistence please let me know and I will try to help you.
Once again, thank you for using visualCaptcha for wordpress.
cheers
