Hey, I just purchased the physical version of BIAB 2011.5, and am running it on OS X Lion.

I'm having problems getting the RealTracks to work, as I've reinstalled the entire program 3 times now.
Whenever I generate RealTracks for any instrument other than drums, there is absolutely no sound. I don't get any error notifications, and the only lead I have is that the physical RealTracks folders all have "no permission" signs on them. I've set the permission for every folder in there to Read + Write, and still I can't even open the folders. I've repaired permissions, etc. with no luck. I've moved the RealTracks folder to a custom location and selected the custom location in Band in a Box itself, and nothing works. I'm really desperate to get this thing working and so far I've found no one with the same issue.
