Pro Site - Super Admin unable to change blog level

In Pro Sites Management
Manage Site: Musician E.G (Blog ID: 2)

I get the message

"Musician E.G" has never been a Pro Site.This site is using different gateway so their information is not accessible.

And so I'm unable as admin to change it to a pro site level

I am using a fresh install of wordpress 3.5.1

Thanks
