I am guessing you bought the tuner used? I am not sure of all the technical details, but when I bought my tuner I had to give them the ECU code from my car, so it seems like maybe they are set up for a specific ECU code, so maybe the tuner your bought is not set up for your ECU?
Another thought -- if the car does not have the factory tune, but instead has some aftermarket tune, the tuner might not be able to "unlock" it ; normally the first thing that a new tuner does is download the factory tune from the car ; but if the factory tune is not there, I don't know what it does.
