Let me preface that I do not work for mp3car.com or any other company, but did you buy it from them? I know if you had you would not have needed to install any drivers. Perhaps by reinstalling them something got crossed up. If you bought it elsewhere, then I'd have to ask the obvious question...Are you sure that all of your wires are connected properly? Is it in your car or are you benchtesting it? As far as the remote, if the battery is in correctly AND you are pointing it ar the IR receiver it should work. Mine came preprogramed out of the box, not sure if Infill ships them that way. I know this isn't much definative help, but in the meantime maybe it will point you in the right direction.
