Error 1003/8003 when downloading iTunes extras for Avatar
So I have recently purchased Avatar, and I saw the nifty iTunes Extras badge, which further encouraged me to buy it.
Lo and behold, I can download the core movie, but the extras won't download. I researched the error codes on the web, tried all the suggestions I could find to no avail. As a last resort I contacted iTunes Store support. They insist the problem is on my end, even after I thoroughly described all the steps I've taken to resolve any possible reasons on my end. They reset something on my account, and I was able to download the artwork, but the file itself (1.7+GB) won't download. Out of desperation/curiosity I clicked the "In the Store" button while viewing the extras artwork. The message there says that the file isn't in their Store - screenshot below:
So I send them this file and the representative STILL wants me to contact AppleCare support for technical support for issues on MY end. Clearly the message in the iTunes Store screenshot above indicates the problem is on their end, and they refuse to fix it, or offer me a partial refund for only receiving half of what I paid for, nor will they issue me a store credit equal to the same.
I realize I'll probably never be refunded or get any kind of a store credit, but I'm hoping Apple does the right thing, or fixes their problem.
I have tried downloading the extras on no less than 3 computers; 2 Windows 7 Pro 64-bit, and 1 27" iMac running 10.8.x. All with the latest versions of iTunes installed, and on no less than 4 different networks.
Anyone else have problems like this?
