Can't Load Sounds/Presets after updates in Steinberg Download Assistant

Hi!

I updated some things in Steinberg Download Assistant and it seems as though a lot of media have disappeared from my Media Library in Cubase. I keep getting these messages when I try to load some meadia into my project. I think i’ve managed to scan my computer for sounds in the MediaBay but everything seems a little messed up after the updates.

What can I do?

This is the first message that shows up.
