I purchased an album from the itunes store several weeks ago. It was actually a pre-order. The Album was released on July 30th but has not yet showed up in my itunes library, nor has the money left my account. When I search the itunes store to find the album it says that it has already been purchased and will not let me download it. I have checked my itunes for "available downloads" and I find nothing..any ideas how or where I can download my album???

Thanks
