Al,

If I were reverting to 2009.5 from 2012, I'd be doing this with help from PG Music's support team. The reason I say this is because a new audio stretching routine was introduced to BIAB in ver. 2011. It's possible that this might complicate the easy return to your previous edition if the program is installed on your internal hard drive.

I'd imagine that if you are running the program from a USB drive, you should only need to run the set-up file on the 2009.5 hard drive. As I said, though, I'd check with PG Music.

Regards,
Noel
