Q: Where's my album?

I pre ordered watching movies with the sound off and it came out today so I go on iTunes to see if I can download it and it says that it's purchased so I go into my music and its not there then I go back to iTunes and it's making me buy every song I check my email and iTunes sent me an email saying to begin download click here and I clicked on the link and it sent me to the iTunes home page so I clicked on the album again hoping it would let me do it this time but nothing basically what my question is where's my album and how do I get it?
