I keep getting the error message too, but I have the 10-game DVD pack that came out a year and a half ago so I don't need it. However, I would like to find a place to get that whole series or perhaps even the whole playoff run as I was only 5 when it happened and have only been able to read about it.
I did not watch the whole thing, but i skipped around from beginning to end and some of the middle and it all worked for me. For those who only have the early bit, looks like there was an error in your download, I would delete it and restart the download fresh. (just say yes you want to "buy it" again when you click to get it)
