Ning to Buddypress importer -- multisite install

hi guys,

I need to import users from an existing Ning network into my multisite install.

Problem is I can't access the importer on my multisite install. First off, buddypress options are in the network screen and not the single blog screen as your installation instructions provide.

Second thing is the "Ning Importer" option is not on the network buddypress options panel either.

Where do I need to go for this fix?

Cheers,
-Mikey
