Hi, I'm trying to transition over from Music Maker to SMS and I might have missed something... I had a few "credits" I'd been saving in the Music Maker store so I bought the last few instruments to use them up and they show up correctly in SMS. However, when I try to use any of those instruments in SMS, it says they need to be activated. They work in Music Maker, but not SMS. Any instruments I bought before installing SMS work fine in SMS, but those last 4 do not. I've tried activating them using the web site but it says the order number isn't valid. Is there something I'm missing to get those last few instruments ported over? Thanks!
