I'm in the process of completing Wwise-101, Lesson 1; and have reached the point where I need to create a new sound effect using the, "Create new Sound SFX," icon. However, neither that icon nor any of the other icons in the Project Explorer view's Audio tab are clickable. I tried to use the designated keyboard shortcut to import the audio file I needed into the Default Work Unit under the Actor-Mixer Hierarchy (shift+i), but that wouldn't work either. Why is this happening?
