[Plugin: Auto Group Join] Cannot edit link field–page not found when click "edit"

I LOVE the idea of this plugin, however, when I try to edit the link field (click on ‘edit’ beside the appropriate profile field), I am taken to a screen that says the page cannot be found.

(I am using WP 3.3 and BP 1.5.2.)

Any help would be greatly appreciated.
