WaveLab 7 on Snow Leopard and Digi003

Buy recently WaveLab 7. I’m running on a MAc Pro with Snow Leopard, I can not play audio through me Digidesign Digi 003, can someone help?

The mac usually defaults to built in output.
Go to Applications / Utillities / Audio MIDI Setup /
Select Digi 003 for sound output. (right click Digi 003)
