Halion 6 Trial stand-alone problem

Just downloaded and authorized the Halion 6 Trial. It opens up fine as a stand-alone, but when I go to select the Outputs, there are no choices available. Any ideas! Thanks.

click the gear icon to open the preferences and go to the asio tab and make sure it is using your interface drivers instead of generic asio I just checked and for me if generic is chosen it will show no outputs

Thank you.
Duh…of course.
Now I just have to figure out why there’s no sound. MIDI indicator lights up. Chose 2 outputs under “Master” in Output section. Will read to figure out what the speaker symbol means, because there’s no way to chose both outputs.
