BuddyPress.org

If you are referring to my plugin, as you can see from the info on the WP Plugins Download page, it’s not supported for BP 1.1.1. I have a version partway through dev but it’s not a priority for me atm so will be a little while.

And if you’ve upgraded to the current version from a previous version, that last version checks for any achievements users were eligible for *before* the plugin was installed.
