Recently upgraded to 3.8- Regisration problems now

[toneloc]

I just recently upgraded my forums to 3.8 and now, when someone tries to register for a new account, this message comes up-

You answered the NoSpam! question incorrectly. Please reevaluate your answer or, if you found yourself unable to answer it, you can refresh for another question if the administrator has enabled multiple questions. If you find yourself repeatedly unable to answer the NoSpam! questions, please contact the forum administration.

This will come up regardless of what method of "Human Verification" I choose. It even comes up when I disable the human verification feature.

Ultimately, I do want the human verification feature on. Does anyone know how I can fix it?

Thanks!
