New user Cannot log into C&C online.

Hi. I am trying to get this all runni.ng so I can play kanes wrath.
I am following the guides. I have just made this fourm account. I have validated it with the email and now gone onto the C&C online page to do the server registration. It says log in using the name and password I used to create this forum account. But when I put that in it says usernam or password not valid.

Please help :(
