Video is not working?

I don't have a solid answer for you, but some troubleshooting thoughts:

The video you specified works on my computer, which means the link isn't broken. The fact that you're able to post to the forum, though, means your connection isn't dead, which would be my first thought.

If your connection is working, but very slowly, you might be able to load simple text-based pages like this but have problems with videos. To test this, try to load different Treehouse videos and see if you have the same problem.

Or, there could have been a temporary issue on either end (yours or Treehouse) that is already fixed. Try it again, and maybe it will just work.

You could also have a plugin or compatibility problem. Have other Treehouse videos loaded for you? Is your software up-to-date?

And, of course, the old standard -- when all else fails, restart your computer (and/or reset your router, by unplugging for about 30 seconds) and see if it's different when you come back. I don't have a clue why this works, but it is surprisingly common for inexplicable errors to disappear on restart.

Good luck!
