Hello Noel,

Thanks again for your help; I appreciate it so much.

The songs I'm playing are almost all from Internet downloads. The downloads are older files, and are all MIDI. I previously played (or downloaded and not played previously) the songs through BIAB version 2010.

When I open these files in my 2018 version, BIAB suggests substituting RealTracks for MIDI, for better sound quality. I've been clicking on those messages to accept the upgrade from MIDI to RealTracks, and saving the changed files when I'n done with them.

I have a handful of songs that I created with 2018, and a couple with BIAB 2010. Most are downloads though.

There is one error message that appears every time I begin a BIAB 2018 session. It is error 9997, and appears to alert me about an error with my ability to record. Since I'm not trying to record yet, I haven't addressed these messages. Here is the full startup message from my FlahMessageLog file. It's long but maybe it will mean more to you than to my inexperienced eyes:

What do you think?
Thanks again, Joel
