Renaissance mini

I need help I bought a Renaissance embroidery machine from my guy he sold it to me because he could not get it to work. While running the machine he accidentally cut it off /shut down improperly and of course prodigy will not help the guy out. So now I bought it thinking that they may help me out if I buy a program or trade up for a new one and sure enough they will not help me or return my calls at all. Does anyone have any clues on how I can resolve this program problem. I have navigator I have the dongle that goes with the program I have everything needed to make it run it's just not recognizing the program.
