You'll need to contact Member Services to get this resolved. You can find their contact details at the bottom of this site or the main ISC2 site.
@Joro I see that you're receiving an SSO error. Please contact Member Services at membersupport@isc2.org and include your Member ID. One of our Customer Service Coordinators will be happy to assist!
