S4Studio keeps crashing

I use S4Studio to delete CC that's cluttering up my game, that I no longer want etc. But whenever I go into my library inside the app, it crashes. Doesn't matter what I click on. Sometimes it something different, sometimes I can use it to delete a few objects sometimes just one then crash!

Do I need to update? I'm not super familiar with this app so I'm not sure if its me or the app.
