Manually delete fusion essentials ? Library manager can't delete it'

hi
cubase is complaining about not finding fusion essentials…

i went to the Library manager… tried to reinstall it… no complaints… but still the error shows up on loading cubase.
when i try to REMOVE it, the library manager says it cannot delete it…
there must be a folder (i have a Mac) somewhere where cubase looks to load the packs… maybe i have to go somewhere on my computer and delete something ?
