How do I register my developer account so I can receive updates.

Its been a little while since I have had time to re-up my developer account. I have a couple of test systems that I am trying to patch but all I get is no packages available. I know this cannot be correct since both systems are RHEL 7.6 and I know RHEL 7.7 is now available.

Please let me know how I can re-associate those systems to the developer account

thank you
