G'day Dean.

I guess I should be pleased that you have experienced the same problem, as this shows that I am not alone in this.

I tried, after consulting with PG live help, reinstalling BIAB and the real tracks which came with the 2021 Ultrpak upgrade. This didn't work as the error is still there.

This happens with both 32 and 64 bit versions of BIAB.

The error is getting clever because it will pop up even without sour note fix, or a change of real track. I agree that this is a bit of a nuisance.

Perhaps PG Music can have a look at this for the next update.
