"VST Audio System, Device Failed to Open!"

MacBook Pro, fresh install of Leopard 10.5.2, Fresh install of Cubase 4 with update 4.1.3.

The Problem:
Cubase 4 won't playback audio?! It won't recognize Core Audio/System Audio?

Devices-->Device Setup, where you select your audio driver it reads:

"VST Audio System
Device Failed to Open!"

All my other audio apps work fine, including Cubase 4Ai.


I need to do some remote recording this weekend, any HELP IS APPRECIATED.
