Configuring Ultimate branding for Store Owners

I am trying to customize the black admin bar at the top of the page for registered users with the ultimate branding plugin, and ended up locking myself out of the network admin. How can I configure these settings so they apply to all of the substores but not the MAIN store (and myself included!)?

I want them to be able to get into the backend to list products, view analytics, receive messages and whatnot but that's about it. They do not need to see the "My Stores" dropdown that shows all of the stores - only their own! Please help me.

Thank you!
