Very limited

This is a cool idea, but I cant seem to find any codes that it works with. I keep getting the same 404 error message. If you want to se it work just take a picture of the icon on iTunes and you will get a short video. I have seen it work on one other print ad, but every other one Ive tried has failed. I gave it 3 stars because it does read the codes.
