    CISSP Study Guide registration code fails

    Alain Balz

      I'm trying to register the (ISC)² CISSP Certified Information Systems Security Professional Official Study Guide, Eighth Edition. When i use the access code from the email it says "Invalid access code". How can I get a new access code or any help?  On the contact form for support there is a error from the backend saying that there is a timeout.
