Halo Channel on Windows 10 Preview

I know my problem may be related to the fact that I am running Windows 10 Preview on my laptop, but here it goes anyway… Sometimes, not every time, as I have watched episode 1 once all the way through, it will play for a couple of seconds once I click on the episode then the loading wheel comes up and it skips to the next item to play. It’s kind of obnoxious because I never got my rewards for watching the episode so I kind of wanted to go back and watch it again, but I haven’t gotten it to work all the way through yet.
