Using Pro Tools HD Native Card w/Cubase

Hey Gang,

Anyone know if the Pro Tools HD Native card will run under Cubase with no Pro Tools hardware? I’m using it on a PC with an Apogee Symphony I/O. The drivers installed just fine and it shows up in Device Manager. But when I try to select the “Avid HD” driver, Cubase gives an “Unknown Error” message.

Thanks, mike.
