BuddyPress.org

good afternoon
I have the following problem when the user registers the e-mail sent to the activation is wrong, is as follows:
http://www.xxxxxxx.xxxxxxxxxxxx.com.br/activate/?key=9464d2103b397d71

and should be like this:
http://www.xxxxxxx.xxxxxxxxxxxx.com.br/wp-activate.php?key=9464d2103b397d71

How can I fix?
