Signing up problem

Hi,
I’m trying to sign up to akismet but it is telling me that I need a WordPress.com account.

I don’t have a wordpress.com blog, I just have wordpress (the wordpress.org open source solution) installed on my website.

What should I do to get the API key?

This is a pic of what I’m seeing when I try to sign up for a Pro Akismet account – http://ge.tt/6tqwmYc/v/0?c

Thanks,
Jeff
