Replying to PBP online store?

 bought how we livin today off the store, and then it plugs it to your itunes or some stupid thing. i wish they would just give you a direct download as my itunes keeps downloading them over and over, theres a desktop, iphone and ipod version, and ALL of them once downloaded start right back up again and dont let me watch them or anything, just start downloading again. this is bullshit, ive been at this for like 2 or 3 hours to no avail. help?
