Downloaded Rock Band Track Pack wrong.

I *** up, hence the name. I just bought AC/DC Live track pack for Rock Band and instead of reading the instructions to make sure I was doing it right, I got in a hurry. Instead of accessing Xbox Live through my Xbox 360 Dashboard and then putting in my code,
I did on my computer. Now I cannot find Angus, Malcolm, Bonn, Brian, Cliff, Phil, Simon or Chris. Is there any way to fix this? It says the code can only be used once and I really, really wanna rock. Thanks for any help.

:)

Press the Guide button on your controller and scroll left then choose Active Downloads. If the pack is still listed there you can start the download.

If it isn't you can check your hard drive to see if it's already been downloaded. Perhaps you hopped on to Rockband a little too quickly after adding the code and it hadn't downloaded yet.

 

if its not found that way, scroll to the right select account, select download history and it should be there
