@kdawood the BrighTalk moderator usually states that while the CPEs should be credited to the (ISC)2 account automatically, this depends on two factors:
You've linked your BrighTalk account to your (ISC)2 member ID. If you didn't do that, follow directions here.
You've watched at least 45 minutes of the webinar --- whether live or archived. To confirm that, go to My Account>My viewing history to get a list of what you viewed along with certificates to prove that.
If you do indeed have the certificates, as @AlecTrevelyan said, just add them manually, but ensure that you periodically check your CPE transcript & delete duplicates if they're added later --- you don't want to tempt the auditors. (To be on the safe side, download the certificates)
