Security Badge Status is 0 (Wordpress reinstalled recently)

Hello, I have configured all security features needed for the security badge, but still showing 0.
I have a question. I have reinstalled WORDPRESS after installing s2member and generating Security Encryption Key. And now I am using the same key. Is that a problem?. Do I have to generate a new key? How to know whether a security encryption key even EXIST in my account?.Thanks. Please reply.
