Having the same problem as the rest of you. I am still waiting for a response from Warner Brothers. I have sent in Digital Copy problems to them before and I received a response with-in 3 business day's so I have a hopeful feeling this will be the same thing. If I get a answer sooner the rest then I post it right away.
On a side note, I bought Watchmen with a digital copy and i could not down load it to itune's, The reason was(I had no clue of this) the digital copy had expired? So the next time you buy a movie for the digital copy, look on the back and there is a expiry date on it, so be carful to not spend more money when you don't have too.
