Buddypress user activation issue


It appears when one creates an account on my buddypress install, the user receives an activation email link. When the link is clicked it brings them back to site and requests an activation key. I have tried imputting the key.Eg:http://www.mywebsite.com/networking/activate/?key=3fd0064569bd944c6cafa7dc3653abfe using activation key after “=” but it doesnt work.
Can this be resolved or is there a way to just login once activation link is clicked or how do i get activation key to be accepted.

I am using WP 3.5.1 & Buddypress 1.6.4
