Fast track Pro ''Hardware not connected, not streaming'' error ''

[retrotape]

Hi everyone;

I just got this interface from one of my friend and downloaded the latest driver package 6.1.11 on Avid's website but the thing is when I tried to launch the control panel it says ''Hardware not connected, not streaming''
there is also ''register'' button at the right bottom, do ı need to register it? because when I clicked to register, it directs me to maudio's home page and I don't know how to register it, also my friend doesn't have any serial number or sth, How can I register it? Can you please help me to get over that situation?

Thank you!
