Add and Activate your support license keys on the Connections Settings admin page under the Licenses tab.
After you do, you will be notified right within the admin about updates and be able to apply them with a single click like you can with the free plugins from wordpress.org.
You should have receive 3 or 4 renewal reminder emails around the time of the license expiration. Is you email address current? The customer record say it is e******@b******w.com (the numer of asterisks I used are a random number, not representative of the actual number of characters to prevent guessing by others :) ) If your address is correct, perhaps they ended up your spam folder. That should happen because these email are verified and signed which stop email service providers such as Gmail and Outlook from auto filtering to the spam folder.
