So that you can work on your song, it should be possible to open BIAB from the USB drive of a previous version of the program if you still have the drives. This would, at least, let you finish your song.

I just tried my drive from last year and Realband 2023 started and worked fine even though I have 2024 installed on my computer. Again, just make sure to point to the the program and the Realtracks and Realdrums on the 2023 USB drive.

Thanks for another suggestion, Noel (I don't know what we would do without you!)
I'll give that a try.
In fact, that gives me an idea I had not thought of. I miss the harmony function that got replaced. I think 2020 was the last time the old one worked. I might try the 2020 version to see if I can get the old harmony engine....
I'll let ya know...
