I bought new songs for Rock Band on my Wii and it shows as downloaded but doesn't actually play. What do I do?
First, try deleting the track and then re-downloading it. Make sure you have an uninterrupted internet connection for the duration of the download.
If you still cannot play it after completing this process then contact Nintendo Consumer Services directly. They'll be able to reset the purchase for you and ensure that your download occurs properly.
