You should try the notation window in Band-in-a-Box to see if you've successfully installed the fonts. If you ran the installer, but don't have the fonts installed, then you'd be the only customer (out of thousands) that's been unable to install the fonts. In this case, it would likely be due to some anti-virus or firewall-type program blocking you from installing anything to the System folder. And of course reboot your system, since you've been reporting all kinds of problems (audio, disk copying, font installation etc.)
