Thanks, yes, everything is in my account, but it was not necessary to download anything since Sforzando is installed and I found the HI-Q sounds installed in C: \ Program Files \ PG Music Inc \ Band-in-a-Box Sounds.

There in the 'Programs' folder are all the sounds that I think Sforzando should find, but it keeps giving the same error "Instrument [name] from bank:2050 was not found!" when I open Sforzando

It is important to note that I can load the instruments manually since in Sforzando plugin GUI them appear listed en el menu Instrument / User / Program. But aren't that patches supposed to be loaded by selecting them on the instrument track? where btw they are ALL listed.
That error message is becoming annoying!
