Jam Packs not showing up.
I updated to Mavericks and have GarageBand 6.0.5. When I opened an old file, the jam Packs show up in the Browser drop down, but there is nothing in the instrument list. When I play the file, it is using the wrong instruments. How do I get the Jam Pack instruments to load in again. I have Mainstage 3, so I know the content is there.
OS X Mavericks (10.9)
