Effective July 1, the ARRL is upgrading its website SSL (Secure Socket Layer) certificate in an effort to keep up with industry standards.

This upgrade only affects HTTPS (secure) pages on the ARRL website, including the e-store checkout pages, any pages that accept donations, or pages that allow amateurs to join the ARRL or renew their memberships. As a result of this upgrade, users running Windows XP Service Pack 2 or earlier Windows operating systems will not be able to access these pages.

To ensure uninterrupted service, Windows XP Service Pack 2 users are encouraged to upgrade to Service Pack 3, or Windows 7 or 8.

If you are unaware of what Windows operating system you have, go to http://support.microsoft.com/kb/322389.

If you have any further questions or problems updating, please contact your local computer technician or service center.
