OK. Followed steps 1-3, and no change (still no sound in Realband, but BIAB works for both MIDI and Audio).

I purchased my BIAB/RB as a download and the .exe file is a "Full" for both (bbrb2010full). If I run that to re-install Realband per Step 4 won't I also reinstall BIAB? Since that program is working, I am hesitant to do that.
