WP Smush Pro on multisite

When I switched over from single to multisite, it's not allowing me to use Smush Pro. So I uninstalled and reinstalled and that didnt seem to help. Even without having the free version installed, it's still defaulting my pro version to a free version. Also it seems the free version isnt recognizing my previously smushed files. It's saying I have 35,000 unsmushed files, which isnt correct. Please help.
