Hi,

One way you can fix this is to reinstall the file "hiq_instruments_sforzando.exe". If you have a Band-in-a-Box hard drive you can find this file in the \PGMusic\Installers folder. When you get to the destination directory screen of the installer, set it to the following, if for some reason it's not already:
C:\Program Files\PG Music Inc\Band-in-a-Box Sounds

The installer sets a registry key containing the location of the Band-in-a-Box sounds bank. The Aria engine, which the Sforzando plugin is built on, uses this key to determine the location of the bank.

You could delete the bank that you have installed on your F: drive (I'm assuming that's your USB HD?), since that won't be needed. You probably manually selected a location on your USB drive originally, and it probably got a different drive letter at some point which is why the problem started happening.
