Deleting Scrivener 3 and Reloading

Hi y’all,

Sometimes when I open Scrivener 3 the tool bar is greyed out. Other times I try to change the font and it won’t stay to what I’ve changed it to.
Until I can get these issues fixed I’m using my older version of Scrivener.

Will deleting and reloading Scrivener 3 help with this problem? Maybe not everything loaded correctly the first time?

Thanks so much for the help!
