That tutorial doesn't reference a recaptcha language file, do you have that file in application/language/english?

[eluser]7amza[/eluser]
i translate it and put it in my language folder already

I had the same problem, and it was because I hadn't put the recaptcha.php view on the views folder correctly. Hope it helps.
