Why can't I sign up for the code, but I can sign up for the forum?

The page for creating an account doesn't work. When you enter the captcha info. it just keeps going back to the same page.

Very frustrating. I have tried two different browsers, turned on all my scripting, turned off all my browser protections and signed up for the forum in desperation.

What am I missing...is there some trick to this?

Generally I'm not that dense. Can somebody help please?
