I have had just installed SLED 12 on my dell laptop, and everything is OK. But when I try to register with YaST (SuSE Customer Center Configuration) and use my e-mail and activation code, YaST gives me an error message that says: "ERROR. Registration Failed. Details: HTTP Token: Access denied."

How can I register SLED 12? I have just purchased an activation code, but every time that I try to register, I recive that error message.
