This is what he's talking about
Maybe it is a resistor that smoked, which is no harm, and it might still work. Hook it up correctly and test it. If it's fried you will see the burnt part, which can be replaced. Post a picture in the lab for advice on which part to replace it. Maybe the installer will solder it for you and redo the connections, or you could just fix it yourself, the hard work of installing drivers is already done.
You are in the middle, tough call. Try the installer first, if no help, try the seller. If no help, fix it yourself, or start again at a reputable shop and buy the parts and install from one place.
How did it sound before it blew up?
