Ok, listen up people...
Due to my stupidly high bandwidth over-run (25GB over the limit), I've had to limit the downloading of these files to every other day.
So, if you can read this notice, it means you're trying to download the video(s) on one of those off days.

If you try again tomorrow, you'll be able to download what you want.

It's an arse, I know. But then, you don't have to pay my server costs.
