Supporter - Site Admin Menu Item not showing

Hi,

I've installed and reinstalled Supporter plugin on my WPMU/Buddypress install and had no luck.

I have super admin access and can see the supporter settings in Network Admin.

I can also see the supporter menu item on other blogs registered. However I cannot see the Site Admin menu item where you are supposed to control supporter from.

Bit bamboozled. All latest versions. Help appreciated.

Thanks

Elliot
