Can't get PT to receive input from my keyboard

[Mason]

Hi,
I'm using an M-Audio Radium61 keyboard with PT and Reason. I'm able to MIDI input from my keyboard in Reason, but for some reason PT is not receiving any of the notes.

I've set up a MIDI track, with Input set to InUSBKeystation > All Channels, and the Output to a Reason instrument. When I play notes, nothing shows up in ProTools, in terms of the volume indicator or MIDI notes in the grid.

I'm totally stuck. If I enable the keyboard in Reason, the notes play just fine, but they are recorded in Reason, not in PT.

Any ideas? The instrument seems to be set up right, as PT sees it on the list of MIDI inputs...so what gives?

Thanks!

have you tried : (from ref manual)

"To enable input devices:
Choose : MIDI > Input Device"
