GarageBand Not Recognizing Keystation. Need help.

I have a new 2.4 aluminum Macbook.

I am trying to get my Maudio Radium 61 key workstation to communicate with GarageBand.

I installed the latest drivers for it, my Macbook recognizes it under the midi settings, and GarageBand shows 1 midi input when I plug it in via usb, and reacts to 0 midi inputs when I unplug it. I also start the track as a software instrument.

The issue, only the onscreen keyboard works, the keystation doesn't.

The keystation works with my PC apps such as Reason and Cubase, so I'm not sure what else to do. Any suggestions, troubleshooting, etc.?
