The secure payment certificate for HDCN had inadvertently been allowed to expire several days ago. This resulted in an error message of "untrusted connection" on trying to pay the renewal fee for HDCN via http://www.hdcn.com/subinfo.htm, the HDCN renewal link.
The renewed secure payment certificate is now in place as of 12:30 PM Chicago time. If you had tried to renew and had run into this problem, please try again. The above error message should no longer be displayed as the secure payment certificate renewal has been activated.
You may need to clear your browser cache to clear out the old "untrusted connection" message (hit REFRESH or clear cookies under internet options). Apologies for the problem.
