I'm unable to watch the archived games of Minn St. vs. UAA as well(had to use a zip code of theres). I didn't get a message though. The message I did get from my player is: "Requested file not found. The link you followed may be outdated or inaccurate."
And I was using Media Player Classic with the K-Lite Mega Codec Pack installed which basically lets me watch any type of video format on the net. So it's probably something on there end. I believe I saw at USCHO a UAA fan posted saying that the zip code thing will be fixed by Friday and that we should be able to watch the series with no problem.
