Presonus Firebox, Cubase 5 Help?

I searched for an answer to my question in the forums. No results. So…

I just scored a new Presonus Firestudio Mobile. It’s plugged in, all the lights are on, when I play the indicator lights flash and everything. In Devices > VST Connections it is listed. When I try to record, however, there is no signal. Just a flat line. I’m pretty lost because I had a Mobile Pre USB and it worked, and I followed all the same steps. I’m new to Cubase (and recording in general) so I’m sorry if I’m missing something obvious.

I’m using Windows 7 64-bit and Cubase 5.5.2
