Can't download Transformers: Dark of the Moon. "err 9006"

Question

As the title suggests, I get an "error 9006" message when trying to download Transformers: Dark of the Moon.
I've tried restarting my pc, restarting my router etc. My iTunes is up to date. I've even tried dowloading a random song off iTunes to see if it was my connection to the store. That was fine.
It's been quite a while now and I still haven't received a response from Apple's "customer service".
Anyone know anything about this? It's a very vague error message.

Answer 1

Transformers released in the UK last week and I too had problems downloading the digital copy that came with my blu ray, and today the same problem with the latest Harry Potter.
All other triple play blu rays I have bought have had the digital copy on one of the discs, but these two have to be downloaded via the itunes store.  The Transformers reached 164 Mb and failed with error 50, got it going again and it reached 1.54 Gb of 2.24 Gb, then error 50 and went back to only being 134 Mb downloaded.  Harry Potter has reached 1.20 Gb and error 50 occured - and it has taken 10 hours to reach that!
My broadband is capped at 5 Gb and above that usage I pay per Gb, the Transformers download actually used 3.2 Gb of that 5 Gb, and the Harry Potter has virtually used the rest so instead of being free with my blu ray, they have both cost me around £10 and my data downloads will be slowed down till the end of the month.  (My BB is linked to my work so it is difficult for me to move to an unlimited download provider).
Anyone any idea why this is happening?  Once I have managed to download I will complain to Apple as it is the iTunes download that is failing, but it is a bit daft that WB make you download rather than put the film on a disc.  And their help page is no use as you have to input the name of the film - and guess what, Harry Potter and the Deathly Hallows Part 2 doesn't seem to exist, even though they have probably sold millions of copies since Friday.
