So I updated from BIAB2016 to BIAB2019... and nothing seemed to work. Things were missing and lists were suddenly empty and midi-sounds would sometimes not play and... I was SO close to getting a refund out of frustration.

Then I had dinner and watched a random Christmas sitcom on Nickelodeon where some dude's head catches fire... and calmed down smile

Here's what I did after that and it, almost like Christmas magic, made everything work smile
Maybe it will work for others too.

I went to the main BIAB folder (the one that by default is C/BB)

Inside that folder I went into the folder called 'Preferences'

I deleted everything in that folder (I basically emptied the folder 'Preferences' completely. Actually I moved all the files into a backup folder outside of BB. But the bottomline is I removed the files so BIAB could not see them)


Then I went back to the main BIAB folder (the one that by default is C/BB)

And then into a folder called 'data'.

In that folder I found a program called 'BB_Cleanup.exe' and I ran it straight from there (BIAB was closed the whole time during all this, and I was using the windows-explorer to get to all these folders)

I then clicked the button 'clean up now' and the program ran some lines of text in its window.

I then ran BIAB2019.

And now everything works smile

I guess leftovers from BIAB2016 caused issues that somehow did not get resolved by running the cleanup from inside BIAB2019. Perhaps BIAB, because it was running, locked some folders or files that actually needed to be moved around for BIAB2019 to work correctly. Files and folders that could only be moved when BIAB was closed and the cleanup program was run outside of BIAB.
Or maybe it was just the deletion of all the prefs files that did the trick. I'm not sure, but main thing is this procedure did the trick. Maybe it will work for others as well.

Just wanted to share this smile
