stilllife on No MIDI input from Roland TD-50

Hello, I am trying EZDrummer 2 before purchasing Superior Drummer.
I am playing a Roland TD-50 connected to a new Mac Book Pro.
The MIDI IN works fine on other programs (BFD3 Demo) but I get no MIDI at all in EZDrummer so I cannot use it.
I also have tried to change the midi mapping (set e-drums setting to "Roland") but no luck.

Can you help me out?
Before purchasing superior drummer I would like to be sure that it works properly with my hardware.

Thanks
