Just to add, I have the .dmg files for RealTracks 01 to 277.

Is this all of them? I'm wondering if perhaps I could have missed installing 1 of them (there are 15 files) - is there an easy way to check this (since each .dmg file has different styles, with a non-straightforward mapping between RealTrack number and style).

Also, just to confirm, I have the latest Mac build (184 released on Nov 2).

Again, thanks for any help.
