Why won't it let me register in Minecraft?

For the past couple of days, I've been trying to register. I bought a card for Minecraft. Whenever I fill out my email, etc. And I click "create account" It does nothing!

Go to this page and fill out the form.

Since it was Easter there will probably be a backlog of support requests, but Mojang tend to have good customer support and you should get a fairly fast reply.

Hope you get sorted out.
