Sorry about this one. I did say thinks were broken – but I didn’t intend that to include this part 🙁 I’ve brought that page forward to be fixed this week, so I’ll let you know when you can re-download and try again.
That reminds me of another point to understand. The link in that last blog post will never change, but the files you get will be changing (hopefully for the better) almost every day as I work through every page that needs changing. So when things are fixed, I will be suggesting you simple re-download everything. It will be too messy to do updates any other way.
