Did you set your com port to the right baud rate and settings?
Also, the interaction light will come on even if there's no connection to the laptop. When your engine is on, it will blink repeatedly, regardless of whether there is a connecction.
I had that problem a couple of times and what I did was turn off the car, remove key, close the program and wait a few seconds. Turn car back on and start engine, and finally start the software. The unit should communicate at this point.
