Even i also tried it. But its not working... Hopefully we will find it in next updates.
I have try a fast test in this moment and it works in only 5 minutes. See Pic.
But i think you must check very accurate the access settings from the plugin.
So, it is not useful to change in this way older folder/file names!!!EDIT:Make sure that you set the value for this option: Size of thumbnails to 0.
