How do I unistall Multisite plugin manager

WARNING: Multisite Plugin Manager and the Premium Plugins module are incompatible. Please remove Multisite Plugin Manager.

How do you uninstall the Plugin manager -- it tells me I can not delete it because it is active in my main site -- but it is not -- it does not even show up on my main site ---
I chose pro-sites cause the Multisite plugin manager never shows up in the list above

I have tried network activating it again --- and then it shows up -- but there is no way to deactivate it on the main site ---- and when I deactivate it on the network admin -- the message does not go away - and it wont let me delete it -- cause it says it is still active on the main site ---
