I haven't tried anything else, but since the first thing I've noticed was that the sliders are still not moving when changing presets, I immediately uninstalled.

Only to find that the uninstaller does not function anymore.

What is going on??!

Anyhow, luckily the uninstaller lists the location of every component, so I just trashed them manually.

I don't think anything should be said against the developer, since it seems he's working hard at releasing frequent updates - I'm sure he's not very happy with how things turned out, so hopefully we'll see the app reemerge into it's past glory soon.
