Arthur,
We're investigating. Facebook changed something last night that is breaking how we save settings in Autotune. We're looking into the cause and will hopefully have an update out soon.
It looks like you've run Autotune recently. There haven't been any substantial changes in the recommendations our tool would make right now. If you are having issues though, please let us know, and we'll gladly help you update things as necessary.
Thanks,
Alex
