I am running 1.6 beta on OSX and SC5000M. When I sync on my mac to DropBox, the Engine Library is created and the files m.db etc are updated. However, the MUSIC folder is not created. WHen I sync to a USB drive the MUSIC folder is created within Engine Library. On my SC5000M I get an error that it cannot find the dropbox link when trying to Load a track from a dropbox playlist or crate.
