vstpresets not importing in 7.5

Recently switched from Cubase 5 to 7.5. Over the years I built up many saved patches for my instruments, all in the form .vstpreset. In 7.5, I installed an instrument, and copied over all of my .vstpresets. I then used MediaBay to scan that folder which in the past, always worked for me for re-associating these to whatever instrument they belonged to. This is not working any longer. I scan the folder where the copied .vstpresets live, and they still do not show up for use in the instrument.

Thank you for your help!
