Marty, I know you solved your problem - great. Couple of quick comments:

It's not a bad idea to run Opt., What Add-ons Do I Have every so often. I've also noticed that the yellow or green info caution boxes that appear in the upper right can point me to problem solutions if something isn't right. I have done a custom BIAB install for years, with only the RealTracks I use on a different internal drive from the program.

Your other comment about having audio software on one drive and the audio data on another, is standard practice on pro setups. I know many who have the application program on the boot drive with the OS, the data files on a separate drive, and the streaming audio samples on yet a different drive. Perfectly normal if you are trying to maximize performance. I don't think it makes much of a difference with BIAB, but if you were trying to run a DAW with all kinds of virtual instruments and processing effects, it might give you a few more tracks before your system said Uncle.
