Unable to mixdown external audio processed through Virus Ti (Cubase 4.5.2)

[Hell Yeh]

Something weird that I just noticed, too... since I updated to OS 3.0, it seems as if the inputs on my Virus (both analog and digital) stopped working. I did a S/PDIF loopback test and the ports on my interface appear to be working. And thus, atomizing no longer works.

I've also tried going analog out of my interface to the analog ins of the TI and got the same results. I've tried it with both Pro Tools M-Powered 8.0 and Cubase 4.5.2. Even just trying to go out of iTunes into the TI doesn't yield any results.

I'm on Windows XP Home SP3 and using an M-Audio Profire 2626, with the Virus TI Polar connected to the computer via USB and to the 2626 via S/PDIF in and out.
